get_lm_input: Get Linear Model Input Data

In RobinCar2: ROBust INference for Covariate Adjustment in Randomized Clinical Trials

Get Linear Model Input Data

Description

Prepare the input data for a linear model based on the provided data frame and model formula.

Usage

h_get_lm_input(df, model)

h_get_strat_lm_input(df_with_stratum, model)

Arguments

df	(data.frame) Including the covariates needed for the model, as well as the derived outcome O_hat and the treatment factor.
model	(formula) The right-hand side only model formula.
df_with_stratum	(data.frame) A data frame with an additional column for the stratum, as returned by h_strat_derived_outcome_vals().

Value

A list containing for each element of the treatment factor a list with the corresponding model matrix X and the response vector y. For the stratified version, the model matrix X includes the .stratum column.

Functions

• h_get_lm_input(): Get the linear model input data for the overall data set.

• h_get_strat_lm_input(): Get the linear model input data with attached stratum column.
