Examples

n <- 100
d <- 4

V <- matrix(rnorm(4*n, 0, 1), ncol=4)
V <- as.data.frame(V)
names(V) <- c('v1', 'v2', 'v3', 'v4' )

covariates <- names(V)


formula <- y ~ 1 + v1 + v2 | 1 + v1 | 1 + v1

names_cat <- formula_list(formula)

data_stack_construct <- data_stack_dirich(y          = as.vector(rep(NA, n*d)),
                                          covariates = names_cat,
                                          share      = NULL,
                                          data       = V,
