News for package 'fSRM'
Version 0.6.5
Changes
Fixed some
return;calls in the import function.
Version 0.6.4
Changes
Minor changes to provide a clean R CMD check
Version 0.6.3
Changes
Minor bug fix in import()
Version 0.6.2
Changes
Updated the
importfunction so that three indicators are possible.Fixed minor error in examples.
fSRM now gives an error if users try to compare more than two groups.
Updated CITATION file
Version 0.6.1
Changes
Changed order of dyads in the mean-structure plot. Order now is the same as in the variance-decomposition plot.
Version 0.6
Changes
Prettier output for
equalMeansfunction.Fixed a bug when variances where constrained to be positive in a model with group comparisons and no mean structures: In this case, only the variances of the first group were constrained. Now it's fixed: both groups are constrained.
Added new data sets: clinical, clinical.wide, two.groups, two.groups.wide
When running a two-group analysis, plots automatically show both groups side-by-side
Fixed a bug where the ordering of labels in the meanstructure-plot was wrong
Version 0.5
Changes
Removed
setZerooption fromfSRM. Replaced it with the optionnoNegVar. If this is TRUE, all variances are constrained to be > 0. (Older publications contrained negative variances to be exactly zero. This, however, leads to a distortion of the df). By default, this option is turned off, as negative variances should be recognized as an indicator of model misspecification.Added
rolesEqualoption tofSRM: Do roles matter at all? Compare a model with free roles (m1 <- fSRM(..., means=TRUE, rolesEqual = FALSE)) and a model with equal roles (m2 <- fSRM(..., means=TRUE, rolesEqual=TRUE)) usinganova(m1$fit, m2$fit). This is a model with no mean difference, the actor variances equal, partner variances equal, relationship variances equal, and the respective reciprocities equal (Thanks to a suggestion of David Kenny).If missing values are present, by default
missing = "fiml"is set, and a warning is issued that this is only valid if the data are missing completely at random (MCAR) or missing at random (MAR). Usemissing = "listwise"to exclude families with missing values.Moved all dependencies to
Importsso that no manual installation of packages is necessary for unexperienced users.By default, one-sided p values and CIs are printed for variances.
Added plotting methods for fSRM objects:
plot(x)gives a plot of the relative variances;plot(x, means=TRUE)gives a plot of the mean structure decomposition.Significance stars are printed in the output & nicer formatting of p values.
Version 0.3.5
Changes
Bootstrapping standard errors now properly works (set
se="boot"in thefSRMfunction.)Out-of-bound estimates of correlations are set to NA in the output.
Version 0.3.3
Changes
Re-included the
importfunction, and added thegetImportfunction. These functions can be used to import and transform a data set in wide format.Added parameter
pairwiseto thefSRMfunction (you also have to setmeans=TRUEthat it becomes active). This provides all pairwise comparisons of actor and partner means between roles (e.g., is the actor mean of mothers higher than that of fathers?)
Version 0.3.2
Changes
Fixed a bug in print.fSRM (Differences of variances between groups were printed incorrectly)
Included examples in the fSRM help file.
Version 0.3.1
Changes
Pretty inst/News.Rd file
Minor changes for passing R CMD check ...
Version 0.3
New Features
renamed data sets and changed some column names from the output
Now works with missing values. Default behavior: Families with missing values are excluded (listwise deletion). Set
fSRM(..., missing="fiml")for ML / FIML estimationMore consistent behavior of parameters
means,diff, andgroupin fSRM. It does now that what would be expected.
Version 0.2.6
New Features
mod() function now works with mean structure and delta method if lavaan >= 0.5.16 is installed
added a data set based on Eichelsheim (2011):
data(two.groups)Fixed minor bug in print.fSRM with multiple groups
Now prints a warning if it is attempted to automatically set negative variances to zero in the multiple-group case (Not implemented yet).
Added helper functions which help to import data sets from different formats: 'import()'
Negative variances can be automatically set to zero:
setZero = "negative", or set all non-significant variances to zero: setZero ="nonsig". Please note: The purpose of this function is to reproduce published results; usually it is *not* recommended to set non-significant variances to zero! This parameter does not work yet with multiple groups.Included two data sets, based on Bill Cook's (2000) study: Attachment anxiety in 4-person families (three.person and four.person, see also http://davidakenny.net/kkc/c9/c9.htm), and attachment dependency (two.indicators)
renamed parameter for 'drop': before:
"reciprocities", now:"GR"renamed parameter for fSRM: before:
"delta", now:"diff"minor fixes
Version 0.2.2
New Features
Delta method now also compares variances between two groups
Delta method works for 3-person families, and with dropping of factors
equalMeans() now provides a Wald test for equality of relationship effect means
New Features
-
dropdoes not remove the factor, but rather sets its variance to zero. Improved output of the mod() function
Mean structure for 3-person family now works correctly
The family effect now is included in the delta method
Version 0.2.1
New Features
Replaced 'fe' parameter in fSRM by 'drop': Now the user can drop either the family effect, the actor, the partner effects, or the reciprocities when only three members are present.
New function equalMeans() tests actor and partner means for equality
Implemented delta method: all means of two groups can be compared simultaneously. Set
delta=TRUEandgroup='group'in fSRM, and you're done!
Changes
The structure of the raw data is not shown anymore when executing the fSRM function
Fixed some inconsistencies in labeling
Preliminarily dropped analyses with self-ratings (they probably will be added later again)
Removed error correlations type ‘within’: This has been described in the literature, but actually never been used.
