    Thank you for this. I'm using data from questionnaires to test whether self-esteem, self-efficacy, risk taking behaviour and personal growth positively or negatively predict anxiety. I'm in the process of working out the most appropriate statistical test and I think this is the one I need. Thanks again

    Hi Dr. Jeromy, inside the config file you have an extra "v" for the Lavaan package. I couldn't understand why the 'ProjectTemplate' command wouldn't load especially since the package installed correctly. I thought I should mention it just in case others are new like myself. Thanks for this training, btw!

    I’m really happy that you can so effortlessly click through RStudio and display your great uncommunicated awareness of the layout functionality and the fact that one needs to access specific data sets and libraries from some well-kept secret place using some very special clicks that only you are aware of. Please don’t call your video an “Introduction to Lavaan” when you’re not up to taking the time and effort to appreciate that what seems self-explanatory to you, is not for the novice. Unless, of course, there’s something like a “Absolute Introduction to Lavaan” in your mind.

    Hi dear Jeromy Thanks for your excellent video on application of R in various statistical analyses! I wrote my R codes in Markdown, but when I tried to convert codes to HTML, showed this error: Error in .External2(C_loadhistory, file) : 'loadhistory' can only be used in Rgui and Rterm Calls: <Anonymous> Execution halted and for PDF showed this one: Error in .External2(C_loadhistory, file) : 'loadhistory' can only be used in Rgui and Rterm Calls: <Anonymous> Execution halted No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: @t If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex() Otherwise consider MiKTeX on Windows - @t MacTeX on macOS - @t (NOTE: Download with Safari rather than Chrome strongly recommended) Linux: Use system package manager could you please help to resolve this problem? of course, I have TinyTeX on my computer. best regards, Asghar

    Great video! I'd like to know more about the interpretation of the output. E.g., here www.understandingdata.net/2017/03/22/cfa-in-lavaan/#output they say the following: "The next kind of operator in the table is ~~. This means covariance, or, when it’s between a variable and itself, variance. The variances of observed variables are the error variances"... Is that so? if that is, can I drop items with the largest values on that?... is there any interpretation of what is considered large or small error variance?.... etc.
