glm_mverse fits glm across the multiverse according to model specifications provided by formula_branch. At least one formula_branch must have been added. You can also specify the underlying error distribution and the link function by adding a family_branch. If no family_branch has been provided, it follows the default behaviour of glm using the Gaussian distribution with an identity link.

glm_mverse(.mverse)

Arguments

.mverse

a mverse object.

Value

A mverse object with glm fitted.
