You'll still have k! If the OP is happy to be told that the coefficients are the estimated values of the model with values on the scale of the log odds, then this Q is OK. q-binomial coefficients [z], is q-log-concave in k, settling one of the conjec- tures in [3], In Section 2 we briefly state two well-known combinatorial descriptions of [z], which will be used to obtain the results of Sections 3 and 4. Then the number of its k-order subsets is () Proof: Let = {, ⋯}. Binomial coefficients are used to describe the number of combinations of k items that can be selected from a set of n items. the probability of failure, instead of π_i. i) if the (typical) log-link is used then the coefficients relate log-change in y to log-change in x, and so the interpretation would be the same as for a log-log regression -- roughly speaking they represent "percentage change in y for a 1% change in x" (as long as the coefficient isn't large). Interpretation depends on the link function. syms n [nchoosek(n, n), nchoosek(n, n + 1), nchoosek(n, n - 1)] ans = [ 1, 0, n] If one or both parameters are negative numbers, convert these numbers to symbolic objects. Meaning of binomial coefficient. Since the first binomial is to the power of 1 we can assume the value of the x term if the second binomial is x^2. thanks. First simple approaches for any \(m\) The good news is that there are easy ways to compute the binomial coefficient for any modulo \(m\) - the bad news is that they are not feasible for very large numbers.
