Thanks! But Documentation is just a brief introduction to each distribution. Such as the Normal Mixtures distribution fits a mixture of normal distributions(This flexible distribution is capable of fitting multi-modal data. You can also fit two or more distributions by selecting the Normal 2 Mixture, Normal 3 Mixture, or Other options.). i expect to know when we can choose 2 Mixture or 3 Mixture and whether the more modes to choose, the better.
