Class necsummary of models fitted with the brms package

Source: R/necsummary-class.R

Single models fitted with the bayesnec package are summarised as a necsummary object, which contains the original brmsfit object summary, the name of the non-linear model fitted, whether this model is an ECx-type model (see details below), and the ECx summary values should the user decide to calculate them.

Details

See methods(class = "necsummary") for an overview of available methods.

Slots

brmssummary

The standard summary for the fitted Bayesian model of class brmsfit.

model

A character string indicating the name of the fitted non-linear model.

is_ecx

A logical indicating whether model is an ECx-type model.

nec_vals

The NEC values. Note that if model is an ECx-type model, this estimate will be a NSEC proxy.

ecs

A list containing the ECx values should the user decide to calculate them (see the non-exported bayesnec:::summary.bayesnecfit help file for details).

bayesr2

The model Bayesian R2 as calculated by bayes_R2.
