Calculate Akaike Information Criterion (AIC) for zero-truncated poisson Distribution

This function estimates the parameters of a zero-truncated poisson distribution from the provided data using maximum likelihood estimation, and then calculates the AIC value based on the fitted distribution.

Usage

util_zero_truncated_poisson_aic(.x)

Arguments

.x

A numeric vector containing the data to be fitted to a zero-truncated poisson distribution.

Value

The AIC value calculated based on the fitted zero-truncated poisson distribution to the provided data.

Details

This function calculates the Akaike Information Criterion (AIC) for a zero-truncated poisson distribution fitted to the provided data.
