Methods to extract coefficients from various cross-price demand model objects.
Usage
# S3 method for class 'cp_model_nls'
coef(object, ...)
# S3 method for class 'cp_model_lm'
coef(object, ...)
# S3 method for class 'cp_model_lmer'
coef(object, fixed_only = FALSE, combine = TRUE, ...)
Arguments
- object
A cp_model_lm object
- ...
Additional arguments (not used).
- fixed_only
Logical; if TRUE, returns only fixed effects. Default is FALSE.
- combine
Logical; if TRUE and fixed_only=FALSE, returns fixed + random effects combined. Default is TRUE.
Value
Named vector of coefficients
A named numeric vector of model coefficients.
Functions
coef(cp_model_nls): Extract coefficients from a nonlinear cross-price model
coef(cp_model_lm): Extract coefficients from a linear cross-price model
coef(cp_model_lmer): Extract coefficients from a mixed-effects cross-price model
