In beezdemand: Behavioral Economic Easy Demand

Summarize a Hurdle Demand Model Fit

Description

Provides a summary of a fitted hurdle demand model, including fixed effects, variance components, correlations, and fit statistics.

Usage

## S3 method for class 'beezdemand_hurdle'
summary(object, report_space = c("natural", "log10", "internal"), ...)

Arguments

object	An object of class beezdemand_hurdle from fit_demand_hurdle.
report_space	Character. Reporting space for core demand parameters. One of: "internal": report internal/fitting parameters (default internal naming) "natural": report natural-scale parameters when a natural mapping exists "log10": report log10()-scale parameters when a mapping exists
...	Additional arguments (currently unused).
