This new normal helps in reaching out the importance of an individualistic approach with the psychological contribution in procuring sustainable thinking. The benefaction of the individual and community helps in understanding these difficult times by accessing some psychological variables such as individual potential, stimulant drivers, identity traits and emotional health. These variables show their involvement in forming an individualistic approach. An individualistic approach will help in developing sustainable thinking which contributes to using the limited resources to the fullest in Covid-19 times. It can be concluded that individuals with high individual potential and stimulant drivers will promote an individualistic approach which promotes sustainable thinking. Emotional health and identity traits help in a flourishing individualistic approach which promotes sustainable thinking. The futuristic approach of the study throws light on the execution of cognitive styles in the individualistic approach which can be altered by individual potential, stimulant drivers, identity traits and emotional health accentuating the approach to stimulating sustainable thinking.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133635416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The period of the study is from 2011-2021. S&P BSE Energy Index consists of 26 companies, but the study has been conducted on 21 companies due to the unavailability of data in the continuous form. While in S & P BSE Power Index, 14 companies are listed, out of which data of 4 companies was not available in continuous form, thus the final power index sample is locked with 10 companies. The results are important for investors to select the stocks of Power and Energy sectors by considering the resultant effective factors of the study. The Random Effect (RE) Model of Panel Regression was applied which shows that Inflation, Interest Rate, GDP, EPS, ATR and CR have significant effect on Stock Prices. The Research Paper is based on the stocks of Power and energy sector which empowers an investor in analyzing the stock by considering these ratios and accordingly they may include the stock in their portfolio and diversify the risk. The study hasn’t covered other economic factors and financial ratios. Other factors and ratios may be considered to know the association with stock return.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125829510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of stock market is to confer capital to companies that they can utilize for funding and spreading their businesses also to serve investors. But it is elusive to prepare right decision for the companies in particular trading of stocks because of dynamic and intermediate nature of the share price. The charge of funding and commercial enterprise possibilities within the inventory market can boom if an efficient algorithm could be developed to predict the price of an individual stock. There are many deep learning algorithms available in which Extreme learning machine (ELM) is one of the most efficient technique for training single layer feed-forward neural networks (SLFNs). Integrating ELM with auto encoder has gotten another viewpoint for extracting features using unlabeled data. This paper attempts to focus on predicting stock market five days ahead by using a new variant of deep neural network i.e multilayer extreme learning machine with auto encoder (MLELMAE). This model is applied on YES, SBI, and BOI datasets there by the performance of the proposed model is measured and compared with other Deep Learning (DL) techniques like Radial Basis Function Neural Network (RBF), Back Propagation Neural Network (BPNN), and ELM in terms of Mean Absolute error (MAE), Mean Square Error (MSE), Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE). The results also show that the proposed model outperforms best over other DL techniques.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"269 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134033079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study empirically investigates 255 Mauritius, mobile payment users, using the survey. Structural equation modeling (SEM) using Smart PLS software has been used to validate the variables and their relationships. Results reveal that social value and utilitarian value positively and significantly influence behavioural value. Conversely, enjoyment value is inversely proportionate and insignificantly influences the behavioural value. Overall, this study projects consumer’s perceptions of value as an influential factor in the adoption of mobile payment in the context of small island economies. This study contributes to the ongoing debate on mobile payment usage and its acceptance in small island states. This research is pertinent and timely as the Mauritian government is working towards the transformation of the island into a digital economy. Further, the findings are important to digital marketers and other professionals who are developing effective marketing tactics to reinforce value to encourage mobile payment.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134018436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such instability and unpredictability resulted in numerous cases of excess stock when demand declined or a shortage of commodities when demand for certain goods increased significantly. The research presented in this paper contributes to modelling and forecasting rice sales demand in a Fair Price Shop (FPS) in Kerala, India by employing a time series technique. Our research shows how past demand data can be used to estimate future demand and how these forecasts impact the Public Distribution System (PDS). Our study employs Autoregressive Integrated Moving Average (ARIMA) and Double Exponential Smoothing (DES) techniques to develop future prediction models that significantly increase the efficiency and accuracy of demand and inventory forecasting. The forecast models generated from past data are verified and validated in the real case application using the Mean Absolute Percentage Error (MAPE) that helps to forecast the demand of inventory required in FPS. The proposed ARIMA and DES outperform the forecasts made by the empirical model, with ARIMA doing better in terms of future forecasts.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126107448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hospital staff have been under unprecedented pressure from a large number of patients, and in some countries, the lack of space for patients at the height of the epidemic has reached a point where hospitals do not have the capacity to accept new patients. Therefore, studying the duration of treatment of COVID-19 patients is very important in managing the ability of treatment staff and hospital facilities. In this paper, the length of hospitalization of all COVID-19 patients in Al-Sadr General Hospital in Al-Amarah, Iraq, is statistically studied from March 2020 to April 2021. The cumulative distribution function (cdf) of the patients’ treatment duration is estimated using Birnbaum-Saunders (B-S) kernel estimator. This estimate allows us to estimate the probability of a patient’s stay in the hospital for a specified period of time. In this paper, we obtain an asymptotic confidence interval for the B-S kernel estimator. However, due to the dependence of the obtained confidence interval on the unknown cdf and its derivatives, we propose a bootstrap algorithm to calculate the confidence interval and use it for the length of hospital stay of COVID-19 patients.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115251447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
