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.
