The simplest motivation for the negative binomial is the case of successive random trials, each having a constant probability p of success. Oct 11, 20 coeficientes binomiales y binomios al cuadrado instrucciones 1. The binomial distribution is used to model the total number of successes in a fixed number of independent trials that have the same probability of success, such as modeling the probability of a given number of heads in ten flips of a fair coin. The number of extra trials you must perform in order to observe a given number r of successes has a negative binomial distribution. Binomial coefficient or all combinations matlab nchoosek. Given a set of points x and a set of values y, i am trying to compute the polynomial that best fits px y in the least squared sense. Matlab command you clicked a link that corresponds to this matlab command. With large n, exact calculations of a binomial distribution can be very time consuming. The best i could find was nchoosek, but for some inexplicable reason this function only accepts integers not vectors of integers.
Calling nchoosek for numbers that are not symbolic objects invokes the matlab nchoosek function. Alternatively, one or more arguments can be scalars.
