Sample size for non-inferiority trial(SSNI) computes sample size for non-inferiority trial with additive and multiplicative margin. It is designed to compute the sample size allocated for both treatment and control group. The efficiency of optimal allocation compared to (1:1) equal allocation is reported.
The first major release of SSNI will be added to CRAN. Until then, the easiest way to install IRCT is as follows:
devtools::install_github("https://github.com/thevaa/SSNI")
