Alternatively, you can think of GLME models as a generalization of linear mixed-effects models (LME) for data where the response variable is not normally distributed. A mixed-effects model consists of fixed-effects Description. A typical workflow involves these steps: import data, fit a generalized linear model, test its quality, modify the model to improve its quality, and make predictions based on the model. b is a vector of coefficient estimates as returned by the glmfit function. plot creates an added variable plot for the model as a whole (except a constant term ) if the model includes multiple terms. You also can use the MATLAB polyfit and polyval functions to fit your data to a model that is linear in the coefficients. For example, you can specify the covariance pattern of the random-effects terms, the method to use in estimating the parameters, or options for the optimization algorithm.
