link

Link function abstraction for MMM models.

Provides the LinkFunction enum and the LinkSpec strategy hierarchy that centralise all link-dependent logic (inverse link, default likelihood, default intercept prior, target validation, and total-media contribution graph construction).

Functions

get_link_spec(link)

Return the LinkSpec instance for link.

Classes

IdentityLinkSpec()	Identity link: E[y] = mu * target_scale.
LinkFunction(*values)	Supported link functions for the MMM.
LinkSpec()	Strategy object that centralises all link-dependent behaviour.
LogLinkSpec()	Log link: E[y] = exp(mu) * target_scale.
