In mverse: Tidy Multiverse Analysis Made Simple

Fit generalized linear regression models across the multiverse.

Description

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.

Usage

glm_mverse(.mverse, parallel = FALSE, progress = FALSE)

Arguments

.mverse	a mverse object.
parallel	passed to multiverse::execute_multiverse() to indicate whether to execute the multiverse analysis in parallel. Defaults to FALSE.
progress	passed to multiverse::execute_multiverse() to indicate whether to include a progress bar for each step of the execution. Defaults to FALSE.

Value

A mverse object with glm fitted.
