In sqyu/ZiDAG: Directed Graphical Models and Causal Discovery for Zero-Inflated Data

Description

Calculates the BIC score from a fit result.

Usage

bic_from_fit(fit_res)

Arguments

fit_res

A list returned from zi_fit() or .res_from_model_fits() with value_only == FALSE.

Details

Returns bic_score(fit_res$nll, fit_res$n, fit_res$effective_df).

Value

A number, the BIC score.

Examples

Y <- matrix(rnorm(500) * rbinom(500, 1, 0.7), nrow=50)
res <- zi_fit(Y != 0, Y, 1, 2:5, value_only=FALSE)
bic_from_fit(res)
bic_score(res$nll, res$n, res$effective_df)
