This page documents important updates and additions to the Mplus syntax, lavaan code, or the FAQ.
| July 21st, 2022 | The FAQ has been updated with information on how to impose constraints such that the standardized lagged effects can be made time-invariant. Mplus and lavaan model syntax for specifying such a model have been added as well. |
| June 28th, 2022 | The answer to the FAQ regarding an RI-CLPM for three or more outcomes has been updated with new examples of researchers applying a trivariate RI-CLPM. |
| May 17th, 2022 | The FAQ has been updated with a link to the
powRICLPM R-package. This package is currently developed to
allow for user-friendly power analysis for the RI-CLPM. |
| November 23rd, 2021 | Residual
model syntax specifications for Mplus have been added, in which the
new “hat-notation” of Mplus version 8.7 is used, as well as
PON and PWITH statements to allow for simpler
input files. Furthermore, the FAQ was updated with the latest
information on the
RI-CLPM for categorical variables, and a new question and answer
concerning development
over time in the RI-CLPM was added. |
| July 7th, 2021 | The FAQ has been updated with an informal response to some of the conclusions drawn by Orth et al. (2021) regarding the use and appropriateness of the CLPM and RI-CLPM. |
