|
parameter |
A vector of the parameters of the model which is set to initial estimates on function call. |
model.type |
Takes one of two values i.e. 'p only' or 'p and scale-factor'. The 'p only' value fits a linear predictor function to the parameter p which is the 'm(1)' in equation (6) of Faddy and Smith (2012) divided by 'N'. The 'p and scale-factor' value fits linear predictor functions to both p and the scale-factor. |
model.name |
If model.type is 'p only' the model being fitted is one of the six 'binomial', 'over-dispersed-one', 'over-dispersed-two', 'generalized binomial', 'beta binomial' or 'correlated binomial'. If model.type is 'p and scale-factor' the model being fitted is one of the three 'generalized binomial', 'beta binomial' or 'correlated binomial'. |
link |
Takes one of nine values i.e., 'logit', 'probit', 'cloglog', 'cauchit', 'log', 'loglog', 'double exponential', 'double reciprocal', 'power logit'. The default is 'cloglog'. The 'power logit' has an attribute of 'power' for which the default is 1 i.e., a logit link. |
ntrials |
This is a scalar representing the denominator i.e., the length of the probability mass function returned is this scalar + 1. |
covariates.matrix.p |
A matrix of covariates for p where rows are the number of values in listbinary and columns the covariates. This matrix is extracted from the formulae in function BinaryEPPM. However, in the accompanying example it is shown how it can be constructed independently of function BinaryEPPM. |
covariates.matrix.scalef |
A matrix of covariates for the scale-factor where rows are the number of values in listbinary and columns the covariates. The default is a vector of ones. This matrix is extracted from the formulae in function BinaryEPPM. However, in the accompanying example it is shown how it can be constructed independently of function BinaryEPPM. |
offset.p |
An offset vector for p. The default is a vector of ones. |
offset.scalef |
An offset vector for the scale-factor. The default is a vector of ones. |
Output which is the output from either Model.BCBinProb, Model.GB, Model.Binary, Model.JMVGB, or Model.ODB.
