Stata package for Structural Equation Modeling with Partial Least Squares (PLS-SEM)

plssem

Current release: 0.6.0

Stata version required: at least 15.1

Stata package for Structural Equation Modeling with Partial Least Squares (PLS-SEM).

The companion package for simulating data in accordance with a given PLS-SEM model is available at the following GitHub repository: https://github.com/sergioventurini/plssemsim.

Installation notes

To install plssem directly from GitHub you need to use the github Stata package. You can install the latest version of the github package by executing the following code in your Stata session:

plssem's Issues

Binary LV error

Hi, I am trying to use the binary(LV) option in plssem but running into issues. When running the model without the binary option, it runs fine with no error, but as soon as I add the binary(LV) option it outputs the following error:

warning: the use of binary latent variables goes beyond the original scopes of PLS-SEM.
They are provided here only for exploratory purposes.
plssem_base(): 3301 subscript invalid
: - function returned error
Mata run-time error
r(3301);

This only seems to occur when the model is more complex. With only a few LVs the function runs with the binary option:
plssem (A < a)(B < b)(C < c1 c2), structural(A B, B C)binary(A). ---> works fine

plssem (A < a)(B < b)(C < c1 c2)(D < d1 d2 d3)(E < e1), structural(A B D, B C E) binary(A) ---> produces above error.

Could you please advise?
Many thanks

Install issue

Hello, I am trying to install plssem. When I copy the text for installing the package, I receive the error code:

Checking package dependencies
installing plssem package dependencies:

http://www.nwcommands.org/ either

1. is not a valid URL, or
2. could not be contacted, or
3. is not a Stata download site (has no stata.toc file).

current site is still https://raw.githubusercontent.com/sergioventurini/plssem/master/

Could you please advise?

plssem_gof() in lplssem, compiled by Stata 17.0 - doesn't work in Stata16

I use STATA 16.1. Below are the command and error message.

(plssem_gof() in lplssem, compiled by Stata 17.0, is too new to be run by this version of Stata and so was ignored)

The PLSSEM cannot be ran after upgrading

The error is: sd(): 3203 [187,11] found where colvector required
