binomial coefficient

[bī′nō·mē·əl kō·ə′fish·ənt]
(mathematics)
A coefficient in the expansion of (x + y) n , where n is a positive integer; the (k + 1)st coefficient is equal to the number of ways of choosing k objects out of n without regard for order. Symbolized (nk); nCk ; C (n,k); Cnk.

Considering the results presented in column (b), we see the sum of the negative binomial coefficients on the term which interacts the low-skilled cohort dummy variable with the cultural distance variable and the term which interacts the low-skilled cohort dummy variable with the cultural distance variable and the lagged immigrant stock variable is significantly different from the corresponding summations for the medium- (p = 0.
