beta_hat {regmedint}

Create a vector of coefficients from the mediator model (mreg)

Description

This function extracts coef from mreg_fit and pads with zeros appropriately to create a named vector consistently having the following elements: (Intercept), avar, cvar (this part is eliminated when cvar = NULL), emm_ac_mreg (this part is eliminated when emm_ac_mreg = NULL).

Usage

beta_hat(mreg, mreg_fit, avar, cvar, emm_ac_mreg = NULL)

Arguments

mreg

A character vector of length 1. Mediator regression type: "linear" or "logistic".

mreg_fit

Model fit object for mreg (mediator model).

avar

A character vector of length 1. Treatment variable name.

cvar

A character vector of length > 0. Covariate names. Use NULL if there is no covariate. However, this is a highly suspicious situation. Even if avar is randomized, mvar is not. Thus, there are usually some confounder(s) to account for the common cause structure (confounding) between mvar and yvar.

emm_ac_mreg

A character vector of length > 0. Effect modifiers names. The covariate vector in treatment-covariate product term in the mediator model.

Value

A named numeric vector of coefficients.
