The generalized Poisson (GP) regression model has been used to model count data that exhibit over-dispersion or under-dispersion. The zero-inflated GP (ZIGP) regression model can additionally handle count data characterized by many zeros. However, the parameters of ZIGP model cannot easily be ...
The Generalized Linear Model (GLM) allows us to model responses with distributions other than the Normal distribution, which is one of the assumptions underlying linear regression as used in many cases. When data is counts of events (or items) then a dis
Performs Generalized Linear Regression (GLR) to generate predictions or to model a dependent variable in terms of its relationship to a set of explanatory variables. This tool can be used to fit continuous (OLS), binary (logistic), and count (Poisson) models. ...
In other words, the formula for fitting is f(μ) = Offset + X*b, where f is the link function, μ is the mean response, and X*b is the linear combination of predictors X. The Offset predictor has coefficient 1. For example, consider a Poisson regression model. Suppose the number ...
Generalized Linear Regression provides three types of regression models: Continuous, Binary and Count. These types of regressions are known in statistical literature as Gaussian, Logistic, and Poisson, respectively. The Model Type for your analysis should be chosen based on how your Dependent Variable...

Poisson regression model is usually used in forecasting claim counts, but when the data appears to be over-dispersed, it will be not suitable. 索赔次数预测模型中通常考虑泊松回归模型,但当索赔次数中出现过离散问题时,泊松回归模型就不再适合。 更多例句>> 3) generalized Poisson's ratio 广义泊松比...
