bcmmrmObject {bcmixed}

Fitted bcmmrm Object

Description

An object returned by the bcmmrm function, inheriting from class "bcmmrm" and representing the Box-Cox transformed MMRM analysis. Objects of this class have methods for the generic functions boxplot, coef, logLik, plot, print, and summary.

Value

The following components must be included in a legitimate "bcmmrm" object.

call

a list containing an image of the bcmmrm call that produced the object.

median.mod, median.rob, median.mod.adj, median.rob.adj

lists including inference results for the model medians for all groups. Levels of the list are time points, where correspondence table is given as time.tbl$code. mod: model-based inference, rob: robust inference, adj: with empirical small sample adjustment.

meddif.mod, meddif.rob, meddif.mod.adj, meddif.rob.adj

lists including inference results for the for the model median differences between all pairs of groups (group1 - group0). Levels of the list are time points, where correspondence table is given as time.tbl$code. mod: model-based inference, rob: robust inference, adj: with empirical small sample adjustment.

lambda

a numeric value of estimates of the transformation parameter.

R

a correlation matrix for transformed outcomes.

betainf

inference results for beta under the assumption that lambda is known. Note that standard errors might be underestimated although statistical tests would be asymptotically valid.

time.tbl

a data frame of a correspondence table for the timepoints.

group.tbl

a data frame of a correspondence table for treatment groups.

inf.marg

a list with results of bcmarg function.

outdata

a data frame where the transformed outcome (ytr), the fitted values on the transformed scale (ytr.fitted), and the residuals on the transformed scale (res.tr) are added to input data.

conf.level

a numeric value of the specified confidence level.
