Extract All Coefficient Types from Cross-Price Demand Models

A convenience function to extract coefficients from any type of cross-price demand model in a unified format. For mixed effects models, returns a list with different coefficient types.

Usage

extract_coefficients(object, ...)

Arguments

object

A cross-price demand model object (cp_model_nls, cp_model_lm, or cp_model_lmer)

...

Additional arguments passed to the appropriate coef method

Value

For cp_model_nls and cp_model_lm, returns the model coefficients. For cp_model_lmer, returns a list with fixed, random, and combined coefficients.

Examples

# \donttest{
data(etm, package = "beezdemand")
fit <- fit_cp_nls(etm, equation = "exponentiated")
extract_coefficients(fit)
#> log10_qalone            I   log10_beta 
#>    0.7430960   -1.1581172   -0.5463001
