Computes Asymptotic Power or Sample Size for Nonlinear Models


Performs the calculations on the following models:

  • Binomial
  • Poisson
  • Exponential Survival
  • Ordinal
  • Multinomial

The models may simply involve k-groups or the outcome may depend on linear combinations of covariates. A generic facility is provided to roll your own for models not incorporated.
