In spsanderson/TidyDensity: Functions for Tidy Analysis and Generation of Random Data

Calculate Akaike Information Criterion (AIC) for Beta Distribution

Description

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

Usage

util_beta_aic(.x)

Arguments

.x	A numeric vector containing the data to be fitted to a beta distribution.

Details

This function calculates the Akaike Information Criterion (AIC) for a beta distribution fitted to the provided data.

Initial parameter estimates: The choice of initial values can impact the convergence of the optimization.

Optimization method: You might explore different optimization methods within optim for potentially better performance. Data transformation: Depending on your data, you may need to apply transformations (e.g., scaling to ⁠[0,1]⁠ interval) before fitting the beta distribution.

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.

Value

The AIC value calculated based on the fitted beta distribution to the provided data.
