P. Albrecht,, A remark on Albrecht's “On the correct use of the Chi-square goodness-of-fit test”, Scandinavian actuarial journal , 1982(3-4), 1982, pp. 168-170
In Albrecht (1980) it was shown that a number of actuarial papers contain some incorrectnesses in using the chi-square goodness-of-fit test (in case of an unspecified parameter θ in the null hypothesis, which has to be estimated from the sample) in connection with claim number distributions.
