Simulation framework

A general framework for statistical simulation.


News

Changes in simFrame version 0.5.3

+ Number of worker processes in examples for parallel computing is now 
  limited to 2.

Changes in simFrame version 0.5.2

+ Bugfix in 'clusterRunSimulation' regarding export of internal object to 
  worker processes.

+ Bugfix in demo for model-based simulation with parallel computing.

Changes in simFrame version 0.5.1

+ Slight optimizations in C++ code to compute inclusion probabilities.

+ Modified vignette according to changes in package 'robCompositions' 
  (function 'invilr' renamed to 'isomLRinv').

+ Moved vignettes to 'vignettes' folder.

Changes in simFrame version 0.5.0

+ Using package 'parallel' now for parallel computing instead of 'snow'.

+ 'runSimulation' and 'clusterRunSimulation' no longer produce a warning 
  when simulations are performed separately on different domains.

Changes in simFrame version 0.4.4

+ Rewrote parts of the C++ code.

Changes in simFrame version 0.4.3

+ S4 generic 'getCall' now has '...' argument to be consistent with 
  R 2.14.0 S3 generic.

+ Updated author affiliation.

Changes in simFrame version 0.4.2

+ Midzuno and Tille sampling now give a warning instead of throwing an error 
  when all inclusion probabilities are outside the interval (eps, 1-eps).

Changes in simFrame version 0.4.1

+ Added column to example data 'eusilcP' that indicates the main income 
  holder of each household.

Changes in simFrame version 0.4

+ Implemented 'runSimulation' and 'clusterRunSimulation' methods for mixed 
  simulation designs.

+ Added control class "TwoStageControl" and corresponding 'setup' and 
  'clusterSetup' methods for two-stage sampling.
    
+ Probability weights or inclusion probabilities for unequal probability 
  sampling can now be supplied by specifying a variable of the population 
  data.

+ Using Rcpp now to incorporate C++ instead of C code.

+ Added functions 'brewer', 'midzuno' and 'tille' for Brewer, Midzuno and 
  Tille sampling, respectively (corresponding to 'UPbrewer', 'UPmidzuno' 
  and 'UPtille' from package 'sampling', but faster C++ implementation).

Changes in simFrame version 0.3.7

+ Added JSS paper to references in help files and vignettes.

Changes in simFrame version 0.3.6

+ Changes in package vignettes.

Changes in simFrame version 0.3.5

+ Improved code in 'CITATION' file.

+ Updated references in package vignettes.

Changes in simFrame version 0.3.4

+ If 'nrep' is not supplied in 'runSimulation' or 'clusterRunSimulation', 
  the corresponding slot of the resulting "SimResults" objects now contains 
  a zero-length numeric vector instead of 0.

Changes in simFrame version 0.3.3

+ Changes in help file for package.

Changes in simFrame version 0.3.2

+ Changes in help file for accessor and mutator functions.

Changes in simFrame version 0.3.1

+ Bugfix in 'clusterSetup' solved problem with inclusion probabilities for 
  group sampling if the data are not sorted according to the groups.

Changes in simFrame version 0.3

+ Control class "NAControl" now allows to specify an auxiliary variable 
  with probability weights for each target variable.

+ To improve computational performance in simulation studies, 'contaminate' 
  and 'setNA' no longer check if auxiliary variable(s) with probability 
  weights are numeric and contain only finite positive values ('sample' 
  still throws an error in these cases).

+ Bugfix in 'setup' solved problem with inclusion probabilities for group 
  sampling if the data are not sorted according to the groups.

+ Classes "SampleSetup" and "SimResults" now contain slots for the control 
  object(s) used.  Accordingly, some redundant slots were removed from 
  class "SampleSetup".

+ Added package 'sampling' to 'Suggests' section of 'DESCRIPTION' file, 
  minimal changes in 'simDensityplot', 'simXyplot' and in help file 
  'tail-methods' so that 'R CMD check' and 'R CMD INSTALL' no longer 
  produce warnings or notes.

Changes in simFrame version 0.2

+ Argument 'average' added to plot function 'simXyplot' that specifies 
  whether the mean or median is used to compute averages.

+ Replaced example data, which is now called 'eusilcP' and has household 
  income components.

+ Added accessor and mutator functions 'getFoo' and 'setFoo' for slots 
  (here "foo" stands for the name of the slot).  If no method 'setFoo' is 
  available, this means that the slot is not supposed to be changed by the 
  user.

+ Renamed slots "group" to "grouping" and "method" to "fun" (where 
  available) since functions named 'getGroup', 'getMethod' and 'setMethod' 
  already exist and cannot be used for accessor and mutator functions, 
  respectively.

+ Renamed function 'getProb' to 'inclusionProb' to allow accessor method 
  for slot "prob".

+ Removed class "SimResult" to avoid confusion.

+ Added 'show' methods and improved existing ones.

+ Added 'summary', 'head' and 'tail' methods.

+ Restructured help.

+ Added demos for design-based simulation, model-based simulation and 
  parallel computing.

+ Classes "SampleControl" and "SampleSetup" now contain a slot that 
  indicates whether groups are collected after sampling individuals or 
  sampled directly.

+ Class "SampleSetup" now contains a slot that stores the seed of the 
  random number generator before and after setting up the samples.

+ Made various improvements for plot functions if simulation results with 
  multiple contamination levels or missing value rates are supplied.

+ Included package vignettes.

Changes in simFrame version 0.1.2

+ Class "NAControl" now contains a slot that specifies whether missing 
  values should also be inserted into contaminated observations.

+ Added 'aggregate' method for objects of class "SimResults".

+ In function 'contaminate', the column ".contaminated" is always appended, 
  even if 'epsilon' is 0 or 'x' does not have any rows. 

Changes in simFrame version 0.1.1

+ Argument 'select' added to plot functions for specifying columns to be 
  plotted.

+ Row names of example data 'eusilc' are now sorted from 1 to the number of 
  rows.

+ Fixed cross-references in some help files.
