Need Help??

I looked at this module, but I don't understand the nomenclature it uses.

My limited background in statistics means that I get the overall methodology, more or less, but am unfamiliar with the jargon.

For example, what is rsq?

And what is the array of theta coefficients?

If I can use this module to get the coefficients I want -- just a constant, a slope, and an error term -- great, but could someone show me how?

I would be a bit less generous: the documentation is poor. Abbreviations and symbols should always be explained. Take a look at just about any paper in a refereed journal.

rsq is probably the square of the correlation coefficient. The θ array is probably the coefficients for x_i.(Note that that's supposed to be a subscript, but it's rendered, at least in my browser, as a superscript).
