Regression Models for Count Data in R

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

How to handle two types of observations in R?

To handle thetwo types of observations, we use two vectors, one for the numbers, another one to indicate ifthe number is a right censored one. In R, we represent the data by In R they are later used as inSurv( stime, status ). Right censoring happens for thecase ofamldata set, variable time and status. Try

What is the use of predict() method?

The predict()method computes predicted means (default) or probabilities (i.e., likelihood contributions) for observed or new data. Additionally, the means from the count and zero component, respectively, can be predicted. For the count component, this is the predicted count mean (without hurdle/in ation): exp(x> i ).

What is a generalized linear model in R?

The classical Poisson, geometric and negative binomial models are described in a generalized linear model (GLM) framework; they are implemented in R by the glm() function (Chambers and Hastie1992) in the stats package and the glm.nb() function in the MASS package (Venables and Ripley2002).
