Dear,
Firstly thanks for your amazing libraries.
Currently I am working to port some R code to Java, and I encounter
some difficulties.
What is the equivalent of:
- the R class "lm" ?
*description*:
https://www.rdocumentation.org/packages/stats/versions/3.5.1/topics/lm
- of intercept: Z ~ y-1 or z ~ 1
*R examples:*
Y ~ A | Y = βo + β1A | Straight-line with an implicit
y-intercept
Y ~ -1 + A | Y = β1A| Straight-line with no y-intercept; that is,
a fit forced through (0,0)
Y ~ A + I(A^2)| Y = βo+ β1A + β2A2| Polynomial model; note that the
identity function I( ) allows terms in the model to include normal
mathematical symbols.
I can guess that some of the equivalent functionality is provided
by the "o.a.c.math4.stat.regression" package:

Gilles
Thanks for your help
