Define a custom family called 'quasiproductr' to be used with the mgcv package.

The quasiproductr family models relationships where the link function is the hyperbolic arctangent (artanh). This family defines custom link, variance, residual, and initialization functions for use with Generalized Additive Models (GAM).

Usage

quasiproductr(link = "artanh")

Arguments

link

The link function to be used. Default is "artanh".

Value

A family object compatible with mgcv, including variance, link functions, and residual deviance calculation.
