Description: The longpower package contains functions for computing
    power and sample size for linear models of longitudinal data
    based on the formula due to Liu and Liang (1997) and Diggle et
    al (2002). Either formula is expressed in terms of marginal
    model or Generalized Estimating Equations (GEE) parameters.
    This package contains functions which translate pilot mixed
    effect model parameters (e.g. random intercept and/or slope)
    into marginal model parameters so that the formulas of Diggle
    et al or Liu and Liang formula can be applied to produce sample
    size calculations for two sample longitudinal designs assuming
    known variance.
