In NicolasJBM/modestim: Functions and interfaces to build, estimate, and report complex models

Description

Create a formula based on lists of variables. All independent variables will be interacted with the moderator if the latter is specified. Controls are not.

Usage

prep_model(dependent = NULL, independent = c(NA), moderator = c(NA),
  control = c(NA), fixed_effect = c(NA), instrument = c(NA),
  cluster = c(NA))

Arguments

dependent	Character string. Dependent variable.
independent	Character string. Variables of interest.
moderator	Character vector. Moderating variable.
control	Character vector. Control variables.
fixed_effect	Character vector. Fixed effects.
instrument	Character vector. Instruments.
cluster	Character vector. Clusterings for errors.

Value

A formula to run in regressions. Interactions are introduced under the form "independent_x_moderator" and therefore the corresponding variable must be created in the dataset.

Examples

library(modestim)
model <- prep_model(dependent = "turnover",
                    independent = c("distributive", "procedural"),
                    moderator = "pay",
                    control = c("age","gender"),
                    fixed_effect = c("team","period"),
                    instrument = c("chock","manip"),
                    cluster = c("country"))
