SpecModel-class | R Documentation |
Classes describing all the parts of a model that can be specified wihout knowing the exact structure of, and, possibly variation in, the data.
The specification might, for instance, contain a list
of main effects and interactions to be included
in a hierarchical model, but not the priors for
themain effects and interactions, which depend
on the length and dimtype
of the dimensions. These are not known until the
relevant data, such as outcome variable y
,
are supplied, which occurs in the call to function
estimateModel
, estimateCounts
,
or estimateAccount
.
call
The original call
to function Model
.
nameY
The name of the outcome variable, which, in models for the data, may be the name of a dataset.
series
The name of the demographic series being modelled. Used only when dealing with demographic accounts.
varsigma
Data-level standard deviation, when this is supplied by the user (and treated as known.)
nuVarsigma
Degrees of freedom for truncated half-t prior for data-level standard deviation.
AVarsigma
Scale for truncated half-t prior for data-level standard deviation.
varsigmaMax
Maximum value for data-level standard deviation.
prob
In a Poisson-binomial model, the probability that a person or event is enumerated and is placed in the correct cell.
lower
Lower limit for the data-level rate, probability, or mean parameter.
upper
Upper limit for the data-level rate, probability, or mean parameter.
tolerance
Small quantity added to lower
or subtracted from upper
when testing
whether a proposed value for a data-level rate,
probability, or mean is within the required bounds.
maxAttempt
Maximum number of attempts at generating a proposal for a data-level rate, probability or mean before giving up and retaining the current value, within one iteration of the Gibbs sampler.
scaleTheta
The standard deviation of the proposal density for Metropolis-Hastings updates of the data-level rate, probability, or mean parameter.
formulaMu
A formula
describing the main effects and interactions in
a hierarchical model.
specsPriors
A list of object of class
SpecPrior
, describing
any non-default priors for main effects and
interactions.
nameSpecPriors
The names of the main effects or interactions that have non-default priors.
nu
Degrees of freedom for TFixed model.
nuSigma
Degrees of freedom for truncated half-t prior for standard deviation in prior (level 2) model.
ASigma
Scale for truncated half-t prior for standard deviation in prior (level 2) model.
sigmaMax
Maximum value for standard deviation in prior (level 2) model.
aggregate
An object of class
SpecAggregate
.
mean
Vector of means in NormalFixed or TFixed model - subsetted to
include only cells that are observed in y
.
meanAll
Vector of means in NormalFixed or TFixed model, before subsetting.
sd
Vector of standard deviations or scales in NormalFixed or TFixed
model - subsetted to include only cells that are observed in y
sdAll
Vector of standard deviations or scales in NormalFixed model, or TFixed model before subsetting.
metadata
Metadata for mean
and sd
.
metadataAll
Metadata for meanAll
and sdAll
.
useExpose
Whether the model includes and exposure term.
In normal usage, it should not be necessary to
access, or even know about, the slots of a
SpecModel
object. The slots are not part of
the API of the package, and may change in future.
Object of class SpecModel
are created
by a call to function Model
.
