DEVIANCE('BERNOULLI', variable, p<, >) |
The DEVIANCE function returns the deviance from a Bernoulli distribution with a probability of success p, where success is defined as a random variable value of 1. The equation follows:
Syntax |
DEVIANCE('BINO', variable, , n<, >) |
Range: | 0 variable 1 |
Range: | n n(1-) |
Range: | n 0 |
The DEVIANCE function returns the deviance from a binomial distribution, with a probability of success p, and a number of independent Bernoulli trials n. The following equation describes the DEVIANCE function for the Binomial distribution, where x is the random variable.
