These software implementations in SAS and R and interactive webtools allow wide application of our methods.
Statistical software – Implementations of analysis methods in SAS and R
webtools – interactive sample size calculation, estimation of percentiles and risk calculators
For completeness we describe two external software packages for biometrical planning of studies and randomization:
nQuery – software for flexible estimation of sample sizes for planned studies
Randomizer – web-based randomization of therapy assignment for mono- and multicenter studies
