  "Description": "Computes power, or sample size or the detectable\ndifference for a repeated measures model with attrition. It\nrequires the variance covariance matrix of the observations but\ncan compute this matrix for several common random effects\nmodels. See Diggle, P, Liang, KY and Zeger, SL (1994,\nISBN:9780198522843).",
