In statistics, a generalized linear model (GLM) is a flexible generalization of ordinary linear regression.The GLM generalizes linear regression by allowing the linear model to be related to the response variable via a link function and by allowing the magnitude of the variance of each measurement to be a function of its predicted value.. Generalized linear models were About 68% of values drawn from a normal distribution are within one standard deviation away from the mean; about 95% of the values lie within two standard deviations; and about 99.7% are within three standard deviations.

In other words, it is the probability distribution of the number of successes in a collection of n independent yes/no experiments With finite support. Marketing researchers use discrete choice models to study consumer demand and to predict competitive business responses, enabling choice modelers to solve a range of business problems, such as pricing, product development, and demand estimation problems. with more than two possible discrete outcomes. The binomial test is useful to test hypotheses about the probability of success: : = where is a user-defined value between 0 and 1..
