h_mmrm_subgroup_df {tern.mmrm}

Helper for Extraction and Formatting of MMRM Subgroups

Description

This is an internal helper to extract the correct LS mean estimates and contrast for a specific visit and treatment arm relative to the reference arm for one MMRM subgroup.

Usage

h_mmrm_subgroup_df(
  lsmeans,
  overall_fit,
  is_in_subset,
  visit,
  treatment_arm,
  subgroup,
  var,
  label
)

Arguments

lsmeans

(named list or NULL)
LS mean estimates from fit_mmrm() on this subgroup.

overall_fit

(tern_mmrm)
result of fit_mmrm() on overall data.

is_in_subset

(logical)
specifying which row from the overall data should be used for this subset.

visit

(string)
which visit to extract.

treatment_arm

(string)
which treatment arm to extract.

subgroup

(string)
for labeling in the resulting data.frame.

var

(string)
specifies which variable was used to derive the subset, if ALL then this means the overall data was used.

label

(string)
variable label.

Value

List with estimates (with 2 rows) and contrasts (with 1 row) in the format needed in extract_mmrm_subgroups().
