Abstract

We study the distributions of waiting times in variations of the negative binomial distribution of order kk. One variation apply different enumeration scheme on the runs of successes. Another case considers binary trials for which the probability of ones is geometrically varying. We investigate the exact distribution of the waiting time for the rr-th occurrence of success run of a specified length (non-overlapping, overlapping, at least, exactly, \ell-overlapping) in a qq-sequence of binary trials. The main theorems are Type 11, 22, 33 and 44 qq-negative binomial distribution of order kk and qq-negative binomial distribution of order kk in the \ell-overlapping case. In the present work, we consider a sequence of independent binary zero and one trials with not necessarily identical distribution with the probability of ones varying according to a geometric rule. Exact formulae for the distributions obtained by means of enumerative combinatorics.
