Checks if an object stems from a multivariate response model

Description

Small helper that checks if a model is a multivariate response model, i.e. a model with multiple outcomes.

Usage

is_multivariate(x)

Arguments

x	A model object, or an object returned by a function from this package.

Value

A logical, TRUE if either x is a model object and is a multivariate response model, or TRUE if a return value from a function of insight is from a multivariate response model.

Examples

library(rstanarm)
data("pbcLong")
model <- suppressWarnings(stan_mvmer(
  formula = list(
    logBili ~ year + (1 | id),
    albumin ~ sex + year + (year | id)
  ),
  data = pbcLong,
  chains = 1, cores = 1, seed = 12345, iter = 1000,
  show_messages = FALSE, refresh = 0
))

f <- find_formula(model)
is_multivariate(model)
is_multivariate(f)
