In mmrm: Mixed Models for Repeated Measures

Processing the Formula for TMB Fit

Description

Processing the Formula for TMB Fit

Usage

h_mmrm_tmb_formula_parts(
  formula,
  covariance = as.cov_struct(formula, warn_partial = FALSE)
)

Arguments

formula	(formula) Original formula.
covariance	(cov_struct) A covariance structure from which additional formula parts should be added.

Value

List of class mmrm_tmb_formula_parts with elements:

• formula: the original input.

• model_formula: formula with the covariance term is removed.

• model_formula: formula with the covariance term removed.

• full_formula: same as model_formula but includes the covariance structure's subject, visit and (optionally) group variables.

• cov_type: string with covariance term type (e.g. "us").

• is_spatial: flag indicator of whether the covariance structure is spatial

• visit_var: character with the visit variable name.

• subject_var: string with the subject variable name.

• group_var: string with the group variable name. If no group specified, this element is NULL.

• model_var: character with the variables names of the formula, except subject_var.
