Abnormally wide confidence intervals in logistic regression: interpretation of statistical program results1
This study describes the behavior of eight statistical programs (BMDP, EGRET, JMP, SAS, SPSS, STATA, STATISTIX and SYSTAT) when performing a logistic regression with a simulated data set that contains a numerical problem created by the presence of a cell value equal to zero. The programs respond in different ways to this problem. Most of them give a warning, although many simultaneously present...
متن کاملConfidence Intervals for Nonparametric Regression
In non-parametric function estimation, providing a confidence interval with the right coverage is a challenging problem. This is especially the case when the underlying function has a wide range of unknown degrees of smoothness. Here we propose two methods of constructing an average coverage confidence interval built from block shrinkage estimation methods. One is based on the James-Stein shrin...
متن کاملConfidence regions and intervals in nonlinear regression ∗
This lecture presents some methods which we can apply in searching for confidence regions and intervals for true values of regression parameters. The nonlinear regression models with independent and identically distributed errors and Lp norm estimators are discussed.
متن کاملBootstrap confidence intervals of CNpk for type‑II generalized log‑logistic distribution
This paper deals with construction of confidence intervals for process capability index using bootstrap method (proposed by Chen and Pearn in Qual Reliab Eng Int 13(6):355–360, 1997) by applying simulation technique. It is assumed that the quality characteristic follows type-II generalized log-logistic distribution introduced by Rosaiah et al. in Int J Agric Stat Sci 4(2):283–292, (2008). Discu...
متن کاملConfidence intervals for nonlinear regression extrapolation
The various methods of confidence intervals construction for nonlinear regression are considered. The new method named Ž . by a method of associated simulation the AS-method is proposed. Using computerized simulation, it is shown on the example that only two methods, the bootstrap and the AS-method, give a satisfactory accuracy. The advantage of the AS-method is the speed. In comparison with th...
