Assuming a very low contribution of carriers to infection compare to acute infectious, we estimate a probability p(a) (to develop symptomatic Hepatitis B state at age a) and acute carriers’ transmission rate. The value R0 = 2:67 >1 of the basic reproduction number estimated from data in the east of Cameroon confirms that HBV is endemic in the Baka pygmy group.","PeriodicalId":72412,"journal":{"name":"Biostatistics and biometrics open access journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41574709","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}

Unfortunately, solving the SFDE can be a rather complicated task. Therefore, a novel methodology for solving the SFDE has been proposed in this work. The proposed methodology is to firstly convert the SFDE to its equivalent vector stochastic differential equation (SDE) and solving the obtained equivalent SDE in a usual manner. Comparing to the previous ones [1-3], our methodology has been found to be much simpler. Moreover, it is also applicable to the SFDE of both linear and nonlinear type.","PeriodicalId":72412,"journal":{"name":"Biostatistics and biometrics open access journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47083067","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}

These transformations have already turned the statistical landscape upside down and will continue to do so. In fact, the need for statistical data has changed and evolved in terms of the nature of the statistics, on one hand, and requirements regarding availability, quality and time, on the other hand. Starting from the context described above, the development of ONS-Algeria’s quality approach is essentially based on the capitalization of the work of cooperation with Eurostat on the principles of the European Quality Assurance Framework for Official Statistics (QAF), the option for a participatory and transparent process to enrich this approach and facilitate its appropriation and lastly, conducting the process in stages. In driving the process step by step, to optimize its management, our paper will address the issues related to the design of a roadmap for implementing the Code of Practice (CoP) for the ENP south countries.","PeriodicalId":72412,"journal":{"name":"Biostatistics and biometrics open access journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44956397","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}

Even with a moderate number of parents, say 10, p = in a triallel cross experiment; the number of crosses becomes unmanageable to be accommodated in homogeneous blocks.
