This function carries out goodness-of-fit tests for contingency tables from the power-divergence family.
gof_test(lambda, observes, theoriques)
| lambda | parameter defining the statistic to be used: lambda = -0.5 is for the Freeman-Tuckey statistic, lambda = 0 for the G2 statistic, lambda = 2/3 for the Cressie-Read statistic and lambda = 1 for the classical Chi-square statistic |
|---|---|
| observes | vector of observed probabilities |
| theoriques | vector of theoretical/expected probabilities |
This function returns the value of the goodness-of-fit statistic.
