object

A size biased distribution model of class sbm.

Optional additional sbm objects.

k

Numeric, the penalty per parameter to be used; the default k = 2 is the classical AIC.

Value

A dataframe of AIC values, NA if the model is non-parametric (i.e. fitted with pdf = "none").

Examples

  data(BCI_speed_data)
  lmod_null <- sbm(speed~1, BCI_speed_data, pdf="lnorm")
  lmod_mass <- sbm(speed~mass, BCI_speed_data, pdf="lnorm")
  AIC(lmod_null, lmod_mass)
