Class for a dataset of general estimates with optional degrees of freedom and standard errors.

Details

This object cannot be created directly; use getDataset with est, se, and optionally df to create a dataset of general estimates. If df is omitted, it is internally set to Inf for every stage, corresponding to a normal approximation.

The estimates are endpoint-independent. Test statistics and information are calculated directly from estimates, standard errors, and degrees of freedom. Stage-wise test statistics are calculated as (estimate - thetaH0) / se. Cumulative estimates use inverse-variance weighting, with cumulative standard errors and Satterthwaite degrees of freedom calculated on the same scale.

Fields

stages

The stage numbers of the trial. Is a numeric vector of length kMax containing whole numbers.

estimates

Stage-wise estimates.

degreesOfFreedom

Stage-wise degrees of freedom. If omitted on input, these are set to Inf.

standardErrors

Stage-wise standard errors.
