I had expected those would be added in the new version 13, but it didn't happen. I am not aware of any new LPA/LCA features in Stata 13/13.1 even though the SEM features have been substantially expanded to handle discrete endogenous variables - which is what is needed for LPA/LCA. (By the way, I have successfully replicated the LCA Stata Plugin results in both Mplus and LatentGold using my own data.) (I don't believe you can use Small Stata with the LCAPlugin.) Note: If you have Stata/SE or Stata/MP instead of Stata/IC, you can skip steps 12-14 above, because the maximum matrix size limitations in the higher versions of Stata are much less restrictive. If you have problems, send me a private message via TalkStats and I'll send you my email address via a private message. Run the examples to test your installation of the LCA plugin by running the myLCA.do file.Ģ0. In higher versions of Stata, this may not be necessary.ġ9. In Stata/IC type -set matsize 800, permanently- to increase the mat size to its maximum. Save the modified version of LCA.do with the name myLCA.do.ġ8. This uses only the first 750 lines in the data file.)ġ7. (That's necessary because the matrix size limitation in Stata/IC also limits the number of cases you can analyze. Then change that line to: infile using LcaSampleDataset in 1/750. If you have Stata/IC rather than Stata/SE or higher, find this line near the top of the file: infile using LcaSampleDataset. (Again, that is necessary to satisfy the maximum matrix size limitation in Stata/IC.)ġ6. If you have Stata/IC rather than Stata/SE or higher, then change -maxiter(5000)- to -maxiter(800)- in Examples 2-5. (That's necessary because of the maximum matrix size limitation of 800 in Stata/IC.)ġ5. If you have Stata/IC rather than Stata/SE or higher, then add -maxiter(800)- on a new line below -rhoprior(1.0) ///- in Example 1. If you have Stata/IC rather than Stata/SE or higher, change -rhoprior(1.0) in the first example to -rhoprior(1.0) ///. In that same file, find -rhoprior(1.0)- in the first example.ġ3. Change that line to: cd C:/LCAPlugin/ /*CHANGED TO LCA Plugin Directory ON LOCAL MACHINE!*/ġ2. Find this line: cd D:\project\Stata_lca\Release64\ /*CHANGE THIS PATH TO MATCH THE FILE LOCATION ON YOUR MACHINE!*/ġ1. Using Notepad (or any other plain text editor, but not Word), open the file named LCA.do. Save the modified version of doLCA.ado and do not change its name.ĩ. Change the last line in the doLCA.ado file to: program lca, plugin using("C:/LCAPlugin/lca.dll"). Using Notepad (or any other plain text editor, but not Word), open the file named doLCA.ado. Place the contents of the extracted version of the LCA plugin in the newly created C:\LCAPlugin directory.Ħ. Create a new folder named "LCAPlugin" in the root directory of your C:\ drive.ĥ. Extract either the 32-bit or 64-bit version of the LCA plugin (whichever matches the bit version of your Stata software).Ĥ. Check whether you are using the 32-bit or 64-bit version of Stata by typing in Stata the command -about.
