powRICLPM 0.2.1
Minor improvements and fixes
- Fixed a bug in version 0.2.0, in which some of the column names of
the summary tables from summary.powRICLPM.parameter()andsummary.powRICLM.condition()were misaligned due to a
missing column name.
- Fixed a bug in version 0.2.0, in which population values were not
correctly parsed when setting the constraints = ...argument ofpowRICLPM()to anything other thanconstraints = "none"(the default). This resulted in
incorrect estimates of bias, mean square error (MSE), and
coverage (Cover). Estimates of power, minimum estimate
(Min), empirical standard deviation (SD),
average standard error (SE Avg) and accuracy were
unaffected and thus remained valid.
- Added additional documentation to summary.powRICLPM()about the interpretation of information in the summary table.
powRICLPM 0.2.0
Breaking changes
- The function powRICLPM_Mplushas been superseded bypowRICLPM()where users can now set the argumentsoftware = "Mplus"to use Mplus for their power analysis.
The old function has been removed in this version.
- The bootstrap_repsargument ofpowRICLPMis now deprecated. Instead, Monte Carlo standard errors are now based on
Morris et al. (2017), and available for all performance measures.
- The argument alphahas been superseded by thesignificance_criterionargument.
Minor improvements and
fixes
- The reliabilityargument can now take in a vector of
reliabilities to simulate performance metrics under various levels of
item reliability.
- The powRICLPMpackage now does not import the packagesdplyrandpurrranymore.
- The clipackage is now used for error handling.
- Slight speed and stability improvements when using
software = "lavaan".
- Analysis using lavaannow relies on the defaultlavTestsettings. SettinglavTesttotests = "none"lead to errors on some computers.
powRICLPM 0.1.1
Minor improvements and
fixes
- Now includes the check_Phi()function, which users can
use to check if they have specified theirPhimatrix of
lagged-effects as intended.
- plot()now allows other performance measures, such as
bias, MSE, coverage, to be plotted through its- yargument.
- Mistakes in the model syntax of the estimation model when imposing
stationarity constraints (using
constraints = "stationarity") have now been corrected.
powRICLPM 0.1.0
New features
- powRICLPMcan now save the generated data sets by
specifying a path with the- save_datargument
Minor improvements and
fixes
- The est_MEargument inpowRICLPMhas been
renamedestimate_ME.
- Internal model fitting using lavaannow skips certain
checks to speed up the process.
- The wSigmaargument inpowRICLPMhas been
replaced with thewithin_corargument. Now, only adoubledenoting the correlation between the
within-components needs to specified rather than a correlation
matrix.
- By default, powRICLPMnow discards results from Monte
Carlo replications with inadmissible parameter results, unless bounded
estimation is used (bounds = TRUE).
