WebThe multinomial distribution is a multivariate generalization of the binomial distribution. Take an experiment with one of p possible outcomes. An example of such an experiment is throwing a dice, where the outcome can be 1 through 6. Each sample drawn from the distribution represents n such experiments. WebOct 31, 2016 · Now how can I generate samples given those: In brief, I need a function like X = GMMSamples (W, mu, sigma, d) where W: weight vector, mu - mean vector, sigma - covariance vector, d - dimensions of samples How can I implement it in python ? I found scipy library that has GaussianMixture library.
