fits a linear model with coefficients W to minimize the residual sum of squares between the observed responses in the dataset, and the responses predicted by the linear approximation. Mathematically it solves a
A link function f defines the relationship between μ and the linear combination of predictors. Use the properties of a GeneralizedLinearModel object to investigate a fitted generalized linear regression model. The object properties include information about coefficient estimates, summary statistics, ...
广义线性模型(Generalized Linear Model) http://www.cnblogs.com/sumai 1.指数分布族 我们在建模的时候,关心的目标变量Y可能服从很多种分布。像线性回归,我们会假设目标变量Y服从正态分布,而逻辑回归,则假设服从伯努利分布。在广义线性模型的理论框架中,则假设目标变量Y则是服从指数分布族,正态分布和伯努利分布都属于...

New methods were proposed to estimate such a mean response in generalized linear models; however, this has only been done when there are no random effects in the model. We suggest that, in a generalized linear mixed model (GLMM), there are at least two possible definitions of a treatment ...

Simulating Generalized Linear Models 6 6.1 INTRODUCTION In the previous chapter, we dug much deeper into simulations, choosing to focus on the standard linear model for all the reasons we discussed. However, most social scientists study processes that do not conform to the assumptions of OLS. ...
This MATLAB function creates a histogram plot of the generalized linear regression model (mdl) residuals.
