The world rankings and tournament performances have been compiled for most competitors in the grand slam tennis tournaments and the major golf tournaments in 1993. Tournament performance was related to world ranking and home advantage by using both permutation and normal regression models. Logistic and polytomous regression models were used to examine progression through the tennis tournaments only. Although there was surprising consistency between the various approaches, there was little evidence of home advantage.","PeriodicalId":83973,"journal":{"name":"The Statistician : journal of the Institute of Statisticians","volume":"10 1","pages":"551-559"},"PeriodicalIF":0.0,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87259807","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}

That violation-causing a binary decision, the possible dismissal of a batsman-may have a significant effect on the course of the batting side, and ultimately on the game. Some dismissals are indisputable, but a significant minority are the subject of decisions by umpires. Some of these are complex situations yet need rapid decision-making, and television slow-motion replays have highlighted the problem of apparent misjudgments. The effect of such decisions on batsmen and on innings totals can be simulated and consequently estimated to assess their importance.","PeriodicalId":83973,"journal":{"name":"The Statistician : journal of the Institute of Statisticians","volume":"17 1","pages":"529-540"},"PeriodicalIF":0.0,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85261057","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, the beta distribution is not easily understood and its parameters are not easily estimated. This paper explores the possibility of using the more intuitively obvious triangular distribution as a proxy for the beta distribution. It is shown that the differences between the two distribution functions are seldom significant and a procedure is proposed for estimating the parameters of a triangular distribution on the basis of two extreme percentiles and the median.","PeriodicalId":83973,"journal":{"name":"The Statistician : journal of the Institute of Statisticians","volume":"94 1","pages":"387-398"},"PeriodicalIF":0.0,"publicationDate":"1997-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75954515","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}

Few methods exist that can quantitatively, accurately and easily discriminate between sites that commonly have small and variable observation count periods. One method that embodies all these advantages is the hierarchical Bayesian model, the method proposed in this paper. The particular hierarchical Bayesian approach that we use incorporates expert knowledge about accident sites as a group believed a priori to be exchangeable, the Poisson assumption and a conjugate gamma prior. We then propose three natural strategies for ranking and selecting the most hazardous subgroup of accident locations. Also presented is an especially useful procedure that gives the probability that each particular site is worst and by how much it is worst. All proposed strategies are illustrated using previously published fatality accident data from 35 sites in Auckland, New Zealand.","PeriodicalId":83973,"journal":{"name":"The Statistician : journal of the Institute of Statisticians","volume":"40 1","pages":"293-316"},"PeriodicalIF":0.0,"publicationDate":"1997-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77246528","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 last of these three methods is extended here by way of Holder’s inequality to cover the case when the cost is a linear combination of some power of the stratum sample sizes.

This permits an assessment of only the mean rankings. Such comparisons are here extended to permit linear (mean) and quadratic assessments simul­ taneously by the use of product maps incorporating confidence circles. If the blocks are judges or consumers then differences in quadratic effects can indicate product differences in consensus or market segmentation. Preference ranking to compare products is well known. Statistical procedures are commonly used to verify that apparent differences between products are due to other than chance effects. Anderson (1959) suggested a statistical procedure for comparing t products which had been ranked by n judges or consumers. This procedure is closely allied to Pearson's classical x2-test of homogeneity for a tXt table. Anderson (1959) noted that his proposed test statistic could be partitioned to give more information about the product comparisons. Best (1993) discussed such a partitioning, ob­ taining Friedman's rank test for comparing treatment means and a new statistic for comparing quadratic or dispersion effects. Schach (1979) discussed the asymptotic distribution theory for Anderson's statistic and extended it to balanced incomplete-block designs as well as random­ ized block designs. In this paper we use the partitioning suggested by Best (1993) to produce product reference maps which gr,oUR or classify the products.

Let X and Y be bivariate random variables with cumulative distribution function (CDF) F(x, y; 0), where 0 is an unknown, possibly vector-valued, parameter. To estimate 0 on the basis of an observed random sample from F(x, y; 0), we first express the predicted values of the random variables as functions of 0; then an estimate of 0 is obtained by minimizing the sum of the squares of the distances between the observed and predicted values. In the univariate case, this is straightforward because the inverse of the CDF is a single point, but in the bivariate case the inverse is a surface. We present ways for expressing the predicted values in the bivariate case as a function of 0. The idea is to use the joint and marginal CDFs as the basis for calculating the predicted values as functions of 0, thereby extending the univariate to the bivariate case. The method is illustrated by applications to several bivariate distributions such as the bivariate logistic, Pareto and exponential distributions. Simulation results indicate that the method performs well. The method is also applied to an example of real data. Finally, we briefly discuss possible extensions to the multivariate case.","PeriodicalId":83973,"journal":{"name":"The Statistician : journal of the Institute of Statisticians","volume":"81 1","pages":"355-369"},"PeriodicalIF":0.0,"publicationDate":"1997-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73564818","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}
