<Development version: cSEM 0.4.0.9000 Unreleased

  • Bug fix: fix print method for summarize() when resampling with constant values (weights or loadings) is conducted. The standard error, t-value, p-value and CI are properly set to NA now. (#433)

cSEM 0.4.0 (2021-04-20) 2021-04-19

Major changes

Bug fixes

  • Critical bug fix: calculateVifModeB() did not calculate the VIFs for modeB constructs correctly because of a bug in the calculation of the R^2. PLEASE REVIEW YOUR CALCULATIONS in cSEM version < 0.3.1:9000! (thanks to @Benjamin Liengaard for pointing it out).

  • Bug fix: predict() no longer silently returns empty predictions when .test_data does not contain rownames.

  • Bug fix: calculation of the MSE in modelSelectionCriteria() resulted in a vector of incorrect length. In some cases this affected the computation of “GM” and “Mallows_cp”.

cSEM 0.3.1 (2021-02-14) 2021-02-14

  • Bug fix: summarize() no longer fails when .object is a of class cSEMResults_2ndorder and contains no indirect effects.

  • Add argument type_htmt to calculateHTMT(). type_htmt = "htmt2" calculates a consistent estimator for congeneric measurement models.

cSEM 0.3.0 (2020-12-10) 2020-10-12

  • Add lifecylce badges to postestimation functions.(#376)

  • Some arguments accepted by assess()’s ... argument had not been documented properly. This has been fixed. See args_assess_dotdotdot for a complete list of available arguments.

  • calculateHTMT() now allows users to chose the type of confidence interval to use when computing the critical (1-alpha)% quantile of the HTMT values (#379)

  • testMGD() gains a new .output_type argument. By default (.output_type = "structured"), the standard output is returned. If .output_type = "structured", however, a tibble (data frame) summarizing the test decisions in a user-friendly way is returned. (#398)

  • Remove warning from fit() when polycoric or polyserial indicator correlation is used during estimation. (#413)

  • print.cSEMAssess() no longer prints zero for VIF values of constructs that are not part of a particular structural equation.

  • print.cSEMAssess() now prints the results of calculateVIFModeB(). This had been missing in previous releases. (#384)

  • Breaking: calculateVIFModeB() now returns a matrix with the dependent construct in the rows and the VIFs for the coresponding weights in the columns. Previously, the output was a list.

  • Add model selection criteria. See the calculateModelSelectionCriteria() function for details. As usual, all criteria are available via assess(). (#412)

  • Combine functions for surface, floodlight and simple effects analysis in the doNonlinearEffectsAnalysis() function; Breaking: functions doFloodlightAnalysis() and doSurfaceAnalysis() have been removed!

  • Progress bars are now supported for every function that does resampling. Progress bars are fully customizable via the progressr framework created by

    1. Note: to suppress the progress bar use progressr::handlers("void") and then run your csem commands. (#359)
  • Fix bug in the computation of the Bc and Bca interval. Computation failed for models that had no indirect effects.

  • List element “reliability” of assess() is changed to “Reliability” to be consistent with the naming scheme of the other list elements.

  • infer() automatically computes bootstrap resamples now by default if .object does not have class cSEMResults_resampled already. (#389)

  • Remove .alpha argument from testMICOM(). The argument is no longer required as decisions are made via (possibly adjusted) p-values. (#393)

  • Add checks to plot methods for predict(), doFloodlightAnalysis, and, doFloodlightAnalysis.

  • Several documentation updates and typo corrections.

  • The Fornell-Larcker criterion is now computed by its own function calculateFLCriterion(). Previously, it was only available via assess(). (#387)

  • Implement importance-performance matrix analysis via doIPMA(). A corresponding plot method is also available.

cSEM 0.2.0 (30.03.2020) 2020-03-29

Major changes

  • testMICOM() gains the .approach_p_adjust argument. The argument takes a single character string or a vector of character strings naming the p-value adjustment for multiple comparisons. (#138)

  • Review calculateHTMT(). 1.) Add inference; 2) fix wrong handling of single-indicator constructs (#351); 3) Remove warning produced by calculateHTMT() when the estimated model contains less than 2 common factors. (#325)

  • Breaking: Rename argument in doFloodlightAnalysis(). (#343)

  • New function doSurfaceAnalysis(). See ?doSurfaceAnalysis()(#349)

  • Implement degrees of freedom calculation for second-order constructs.

  • Add new function getConstructScores(). The function returns the standardized or unstandardized construct scores. Requires a cSEMResults object as input. (#340)

  • Fix bug in doFloodlightAnalysis(). There was an internal bug. Earlier versions returned the wrong direct effect. If you have used doFloodlightAnalysis() from cSEM v. 0.1.0 results are likely wrong.

  • Export plot method for cSEMFloodlight objects.

  • Allow users to specify a lavaan model without a structural model. Now, users can specify a model with several measurement equations (via <~ or =~) but no strucutral equations. Instead the correlations between all! constructs must be given. Failing to do so causes an error.

New example data

assess()

predict()

  • Update documentation for predict().

  • Integrate and document cSEMPredict method for generic function plot(). Now users may call plot() on an object created by predict(). (#337)

  • Add the density of the residuals as plot to plot.cSEMPredict(). (#337)

  • Remove argument .only_common_factors for postestimation function predict(). Now predict() retruns predictions for composite models as well. This will break existing code that uses predict(..., .only_common_factors = ...). You will get an unused argument (.only_common_factors = FALSE) error. Simply remove the argument to fix it. (#330)

  • Fixed error in predict() when the dataset used to obtain .object contained a character column. (#345)

Experimental features

  • Add .fit_measures argument to testOMF(). Now other fit measures such as the RMSEA or the GFI can be used as the test statistic. This is a rather experimental feature and may be removed in future versions.

Minor changes and bug fixes

  • Using .approach_weights = "GSCA" for models containing nonlinear terms gives a more meaningful error message. (#342)

  • print.cSEMTestMICOM() no longer prints the decision but additional bootstrap information. (in parts: #339)

  • If the weighting scheme is "PLS-PM" and .disattenuate = TRUE, dissatenuation is longer applied to constructs using modes other than “modeA”" or “modeB”. (#352)

  • Model-implied indicator correlation matrix for non-recursive models should now be calculated correctly. (#264)

  • calculatef2() gives an error when the path model estimator is not “OLS”. (#360, #370)

  • Add .type argument to calculateGFI(). Now GFI based on the ML and ULS fitting function can be computed. (#371)

  • csem() gives a meaningful error when the structural model contains only second-order constructs (#366)

  • Fix bug in testMICOM(). Function produced an error if the data set provided contained more columns than indicators used in the model used for csem(). (#355)

  • Fix bug in testMICOM(). Function produced an error if the data set provided contained an id-column even if the id-column was correctly supplied to csem(). (#344, #338)

  • When calculating the HTMT via assess() the geometric mean of the average monotrait−heteromethod correlation construct eta_i with the average monotrait−heteromethod correlation of other constructs can be negative. NaNs produced are produced in this case and the HTMT was not printed. Added a warning and forced printing the NaNs as well. (#346)

  • Add CITATION file (#331)

  • Add informative error message if .data contains missing values.

  • Update vignettes csem-notation
