exogenous_fn: Modify exogenous variables in data frame

In switchSelection: Endogenous Switching and Sample Selection Regression Models

Modify exogenous variables in data frame

Description

Change some values of the exogenous variables in a data frame.

Usage

exogenous_fn(exogenous, newdata)

Arguments

exogenous

list such that exogenous[[i]] represents the value (or a vector of values of the same size as nrow(newdata)) which will be exogenously assigned to the variable names(exogenous)[[i]] in newdata i.e., newdata[, names(exogenous)[i]] <- exogenous[[i]]. If newdata is NULL and exogenous is not NULL then newdata is set to object$data. This argument is especially useful for causal inference when some endogenous (dependent) variables should be exogenously assigned with some values i.e., in the right hand side of the formula and formula2. The purpose of the exogeneous argument is just a convenience so equivalently it is possible to exogenously provide the values to variables via newdata argument.

newdata

data frame.

Details

This function changes exogenous variables in newdata.

Value

The function returns data frame which is similar to newdata but some values of this data frame are set according to exogenous.
