Glance accepts a mixpoissonreg object and returns a tibble::tibble() with exactly one row of model summaries. The summaries are Efron's pseudo-\(R^2\), degrees of freedom, AIC, BIC, log-likelihood, the type of model used in the fit ('NB' or 'PIG'), the total number of observations and the estimation method.

Value

A tibble::tibble() with exactly one row and columns:

  • efron.pseudo.r2 Efron's pseudo-\(R^2\), that is, the squared correlation between the fitted values and the response values.

  • df.null Degrees of freedom used by the null model.

  • logLik The log-likelihood of the model.

  • AIC Akaike's Information Criterion for the model.

  • BIC Bayesian Information Criterion for the model.

  • df.residual Residual degrees of freedom.

  • nobs Number of observations used.

  • model.type Type of model fitted, "NB" or "PIG".

  • est.method The estimation method of the fitted model, "EM" or "ML".
