75 }. For the general case, however, we must compare the empirical vector of bin counts Nj with the multinomial distribution, which is not pleasant to calculate. We resort to using approximations. ,J , pj > 0 in the limit n → ∞ the following approximation holds: Pmult (N1 , . . , Nj ; n, p1 , . . ,J (Nj − npj )2 npj Nj − npj npj (Nj − npj )3 + ...

At least asymptotically for n → ∞ large values of χ2 give small probabilities.

This term is called the χ2 statistic. At least asymptotically for n → ∞ large values of χ2 give small probabilities. This motivates us to use the χ2 statistic approximatively as a measure for goodness of fit. ,J (Nj − npj )2 npj has a χ2 distribution with J − 1 degrees of freedom. As above, to get a formal decision rule we can fix a critical value χ2crit and reject the hypothesis that the observations (X1 , . . , Xn ) come from independent identically distributed uniform random variables if the χ2 statistic exceeds this value.

Like all programming languages, R has control structures such as loops or conditional statements. In R, however, loops should be avoided if possible in favor of more efficient language constructs (see [25]). 14 (page A-213). 28 Generate a matrix of dimensions (nrow ∗ ncol − 1), length(x) with random numbers and use apply() to avoid the loop. 11 (page 23). Deviations from a linear structure should be considered as fluctuations if they stay within the frame of the simulated examples. If the data set under investigation is too extreme in comparison with the simulated examples, this indicates a contradiction with the model assumptions.
