secondDiff: Calculate Cross-Derivative and its Variability

In davidaarmstrong/damisc_nodep: Dave Armstrong's Miscellaneous Functions

Description

Calculates the cross-derivative required to evaluate interactions in logistic/probit regression models.

Usage

secondDiff(obj, vars, data, method=c("AME", "MER"), typical = NULL)

Arguments

obj	An object of class glm that will be used to find the cross-derivative.
vars	A vector of two variables to be used in calculating the derivative.
data	A data frame.
method	Indicate whether you want to use average marginal effects (AME) or marginal effects at representative values (MER).
typical	A named vector of values at which to hold variables constant.

Value

A data frame with standardized quantitative variables
