What do you know about the LMS software?


While I was digging out the scientific literature on the calculation methods of percentile curves, I came up with a software called LMS (V 1.26) and tried to figure out what it is but found nothing useful. Because when I google "LMS" it returns a long list of another LMS (Learning Management System).

I need help with advice on where to start or how can I find the LMS (the statistical software)?

Does anyone have any experience with LMS software?

Thanks in advance for your contributions.
