McFadden's R2

Calculates McFadden's pseudo R2.

r2_mcfadden(model, ...)

Arguments

• model: Generalized linear or multinomial logit (mlogit) model.
• ...: Currently not used.

Returns

For most models, a list with McFadden's R2 and adjusted McFadden's R2 value. For some models, only McFadden's R2 is available.

Examples

if (require("mlogit")) {
  data("Fishing", package = "mlogit")
  Fish <- mlogit.data(Fishing, varying = c(2:9), shape = "wide", choice = "mode")

  model <- mlogit(mode ~ price + catch, data = Fish)
  r2_mcfadden(model)
}
