Watanabe–Akaike information criterion
In statistics, the widely applicable information criterion (WAIC), also known as Watanabe–Akaike information criterion, is the generalized version of the Akaike information criterion (AIC) onto singular statistical models.
Both WAIC and WBIC can be numerically calculated without any information about a true distribution.
