Description Objects from the Class Slots Methods Author(s) Examples

This function fills the '@densityFunction' slot of a ‘countData’ object. It defines the distribution used to estimate posterior likelihoods, and associated values used in these calculations.

Objects can be created by calls of the form `new("densityFunction", ...)`

.

`description`

:A description of the distribution defined.

`density`

:A

`"function"`

, defining the likelihood of a data array given observed data and hyperparameters.`initiatingValues`

:A

`"list"`

of functions (may be supplied as numerics) that define initial values of numeric prior discovery.`equalOverReplicates`

:A

`"logical"`

, describing which of the hyperparameters are equally marginally distributed over all groups, and which are not.`lower`

:A

`"function"`

, required to define the lower limit of optimisation in the case where only one hyperparameter is *not* equally marginally distributed over all groups.`upper`

:A

`"function"`

, required to define the upper limit of optimisation, as for ‘lower’, above.`stratifyFunction`

:An optional

`"function"`

, used to stratify the data for more accurate prior estimation.`stratifyBreaks`

:An optional

`"numeric"`

, used to define the number of strata in a stratification.`nullFunction`

:An optional

`"function"`

on the hyperparameters, used to generate a one-dimensional distribution which can be partitioned to identify ‘null’ data.`orderingFunction`

:An optional

`"function"`

for ordering the data between groups of a model.`modifyNullPriors`

:An optional

`"function"`

for modifying the priors for the ‘null’ data.

No methods defined with class "densityFunction" in the signature.
