AIC Rating Calculator Online

Show Your Love:

The AIC Rating Calculator acts as a powerful numerical evaluator, facilitating the determination of the Akaike Information Criterion (AIC) based on specific model parameters. The AIC, expressed by the formula:

AIC = 2k - 2ln(L)

Where:

  • AIC: Represents the Akaike Information Criterion.
  • k: Denotes the number of model parameters, reflecting independent variables within a regression model.
  • ln: Signifies the natural logarithm.
  • L: Represents the likelihood of the model, showcasing its adherence to observed data, thereby reflecting its fitting accuracy.

Example of AIC Rating Calculator

To exemplify the calculator's functionality, suppose a regression model comprises 5 independent variables (k = 5) and exhibits a likelihood measure of 200 (L = 200). Substituting these values into the AIC formula:

AIC = 2 * 5 - 2 * ln(200)

Upon computation, the resultant AIC value will be obtained, aiding in model evaluation and comparison against alternative models.
