R2MLwiN (version 0.8-2)

mlwinfitMCMC-class: An S4 class that stores the outputs of the fitted MCMC model.

Description

An MLwiN model run via the MCMC estimation method is represented by an "mlwinfitMCMC" object

Slots

Nobs

Computes the number of complete observations.

DataLength

Total number of cases.

Hierarchy

For each higher level of a multilevel model, returns the number of units at that level, together with the minimum, mean and maximum number of lower-level units nested within units of the current level.

burnin

An integer specifying length of the burn-in.

nchains

An integer specifying number of MCMC chains run.

iterations

An integer specifying the number of iterations after burn-in.

D

A vector specifying the type of distribution to be modelled, which can include 'Normal', 'Binomial' 'Poisson', 'Multinomial', 'Multivariate Normal', or 'Mixed'.

Formula

A formula object (or a character string) specifying a multilevel model.

levID

A character string (vector) of the specified level ID(s).

merr

A vector which sets-up measurement errors on predictor variables.

fact

A list of objects specified for factor analysis, including nfact, lev.fact, nfactor, factor, loading and constr.

xc

A list of objects specified for cross-classified and/or multiple membership models, including class, N1, weight, id and car.

FP

Displays the fixed part estimates.

RP

Displays the random part estimates.

FP.cov

Displays a covariance matrix of the fixed part estimates.

RP.cov

Displays a covariance matrix of the random part estimates.

chains

Captures the MCMC chains from MLwiN for all parameters.

elapsed.time

Calculates the CPU time used for fitting the model.

BDIC

Bayesian Deviance Information Criterion (DIC)

call

The matched call.

LIKE

The deviance statistic (-2*log(like)).

fact.loadings

If fact is not empty, then the factor loadings are returned.

fact.loadings.sd

If fact is not empty, then the factor loading standard deviationss are returned.

fact.cov

If fact is not empty, then factor covariances are returned.

fact.cov.sd

If fact is not empty, then factor covariance standard deviations are returned.

fact.chains

If fact is not empty, then the factor chains are returned.

MIdata

If dami[1] is one then the mean complete response variable y is returned for each chain, if dami[1] is two then the SD is also included.

imputations

If dami[1] is zero, then a list of completed datasets containing complete response variable y is returned.

residual

If resi.store is TRUE, then the residual estimates at all levels are returned.

resi.chains

If resi.store.levs is not empty, then the residual chains at these levels are returned.

version

The MLwiN version used to fit the model

data

The data.frame that was used to fit the model.

An instance of the Class

An instance is created by calling function runMLwiN.

Examples

## Not run: 
# 
# library(R2MLwiN)
# # NOTE: if MLwiN not saved in location R2MLwiN defaults to, specify path via:
# # options(MLwiN_path = 'path/to/MLwiN vX.XX/')
# # If using R2MLwiN via WINE, the path may look like this:
# # options(MLwiN_path = '/home/USERNAME/.wine/drive_c/Program Files (x86)/MLwiN vX.XX/')
# 
# ## Example: tutorial
# data(tutorial, package = "R2MLwiN")
# 
# (mymodel <- runMLwiN(normexam ~ 1 + standlrt + (1 + standlrt | school) + (1 | student),
#                      estoptions = list(EstM = 1), data = tutorial))
