The BIC suffers from two main limitations [7] the above approximation is only valid for sample size n {\displaystyle n} much larger than the number k {\displaystyle k} of parameters in the model. the BIC cannot handle complex collections of models as in the variable selection (or feature selection ) problem in high-dimension.
O i = an observed count for bin i; E i = an expected count for bin i, asserted by the null hypothesis. The expected frequency is calculated by: = (() ()) where: F = the cumulative distribution function for the probability distribution being tested. Y u = the upper limit for bin i,
