The classicalPoisson regression model for count data is often of limited use in these disciplines becauseempirical count data sets typically exhibit over-dispersion and/or an excess number of zeros The former issue can be addressed by extending the plain Poisson regression model in variousdirections: e g using sandwich covariances or estimating
•The predict method can predict probabilities response class-predictions and cumulative probabilities and it provides standard errors and con?dence intervals for the predictions Cumulative link mixed models are ?tted with clmm and the main features are: •Any number of random effect terms can be included

researchers need to install R which is available freely at the Comprehensive R Archive Network (http://cran r-project org) Next open R and then type the following at the prompt: R> install packages("mediation") Once mediation is installed the following command will load the package: R> library("mediation")
A lot of functions (and data sets) for survival analysis is in the package survival so we need to load it rst This is a package in the recommended list if you downloaded the binary when installing R most likely it is included with the base package If for some reason you do not have the package survival you need to install it rst
