The random variable X = the number of successes obtained in the n independent trials. The mean, μ, and variance, σ2, for the binomial probability distribution are μ = np and σ2 = npq. The standard deviation, σ, is then σ = n p q. WebAs we'll see, there are two key differences between binomial (or binary) logistic regression and classical linear regression. One is that instead of a normal distribution, the logistic regression response has a binomial distribution (can be either "success" or "failure"), and the other is that instead of relating the response directly to a set ... chip sim card
