WebIt is commonly stated that the degrees of freedom for the chi-square distribution of the statistic are then k − 1 − r, where r is the number of unknown paraméters. This result is valid when the original data was multinomial and hence the estimated paraméters are efficient for minimizing the chi-square statistic. In inferential statistics, you estimate a parameter of a population by calculating a statistic of a sample. The number of independent pieces of information used to calculate the statistic is called the degrees of freedom. The degrees of freedom of a statistic depend on the sample size: 1.
