Calculate Akaike Information Criterion (AIC) for Zero-Truncated Geometric Distribution

This function estimates the probability parameter of a Zero-Truncated Geometric distribution from the provided data and calculates the AIC value based on the fitted distribution.

Usage

util_zero_truncated_geometric_aic(.x)

Arguments

.x

A numeric vector containing the data to be fitted to a Zero-Truncated Geometric distribution.

Value

The AIC value calculated based on the fitted Zero-Truncated Geometric distribution to the provided data.

Details

This function calculates the Akaike Information Criterion (AIC) for a Zero-Truncated Geometric distribution fitted to the provided data.

This function fits a Zero-Truncated Geometric distribution to the provided data. It estimates the probability parameter using the method of moments and calculates the AIC value.

Optimization method: Since the parameter is directly calculated from the data, no optimization is needed.

Goodness-of-fit: While AIC is a useful metric for model comparison, it's recommended to also assess the goodness-of-fit of the chosen model using visualization and other statistical tests.
