Be able to say whether or not X1-X4 has the same effect on complaints that concerns both boys and girls. In statistics, Poisson regression is a generalized linear model form of regression analysis used to model count data and contingency tables.Poisson regression assumes the response variable Y has a Poisson distribution, and assumes the logarithm of its expected value can be modeled by a linear combination of unknown parameters.A Poisson regression model is sometimes known as a log-linear model . It only takes a minute to sign up. It is a very flexible model, can model nonlinear data, allow different covariance structure for each component, and also cope with multidimensional covariates. The relationship between multivariate risk factors and early mortality after orthotopic liver transplantation were analyzed by stepwise logistic regression.
