[R] [R-pkgs] Update on bpcp R package: Confidence intervals to use with Kaplan-Meier Survival Estimator

R Users, We have updated the bpcp R package. It gives pointwise confidence intervals for a survival distribution from right censored data. It is not based on asymptotic approximations, so it may be used with any sample size, and with any censoring distribution, as long as the censoring is non-

[R] [R-pkgs] bpcp package for pointwise confidence intervals for a survival distribution

Hi all, I just uploaded a new version of the bpcp package. It calculates confidence intervals for a survival distribution for right-censored data using the newly developed beta product confidence procedure. Previously developed methods can have substantial error rate inflation for the lower l

[R] [R-pkgs] update to interval package

Hi all, I just uploaded an update to the interval package that does NPMLE estimates of survival distribution and weighted logrank tests for interval censored data. The update now includes a confidence interval method for the survival that uses a modified bootstrap method. Mike ***

[R] [R-pkgs] update to exact2x2 package

Hi all, I have updated the exact2x2 package. The update corrects an error that can sometimes occur in the confidence intervals when the number of counts are large and tsmethod="minlike". In addition to fixing the bug, the correction gives a much faster method for calculating the confidence inte

[R] [R-pkgs] Update of interval package

Hi all, I have uploaded an update of the interval package, which calculates nonparametric maximum likelihood estimates (NPMLE) of distributions and exact or asymptotic weighted logrank-type tests for interval censored data. An important part of the update is that now the default initial estimat

[R] [R-pkgs] exactci package gives exact binomial and poisson tests and matching CI

I am announcing the release of the exactci package. It calculates exact tests and confidence intervals for binomial and Poisson tests. Here is an example to motivate the package: Suppose you want to see if the observed rates of 2/17877 for group A are significantly different from the observe

[R] [R-pkgs] Update to exact2x2 package: Exact McNemar's test

Hi all, I have updated the exact2x2 package which calculates exact conditional tests and the matching confidence intervals for 2x2 tables. The big change in the update is to allow the option paired=TRUE which gives an exact McNemar's test together with odds ratio estimates and confidence inter

[R] [R-pkgs] new package: interval

I have just uploaded a new package called interval. It does weighted logrank tests (e.g., logrank, Wilcoxon-type tests) on interval censored data. It allows Surv objects and can calculated exact p-values. It calls the perm package, but also allows calculation of scores that may be output to fast

[R] [R-pkgs] new package: perm

Hi all, I have uploaded a new package called perm which does linear permutation tests. It does two-sample, k-sample and trend tests. The package is redundant, since everything it does can be done in the coin package, and it is usually faster in coin. The main motivation is to provide another ch

[R] [R-pkgs] new package: exact2x2

Hi all, I have just uploaded a new package to the ftp site called exact2x2. The package does exact conditional tests for 2x2 tables. Specifically, it does Fisher's exact test and Blaker's exact test (see Blaker, 2000, Canadian Journal of Statistics, 783-798). The motivation for the package is t

[R] [R-pkgs] New package: hbim - Hill/Bliss Independence Model for Multicomponent Vaccines

Hi all, I have just uploaded the hbim package. This package does calculations related to the Hill/Bliss independence model as applied to mulitcomponent vaccines. Specifically, the package caculates expected relative risk and proportion protected assuming normally distributed log10 transformed a
