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?	[reply]

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). emc e^(π√−1) = −1	[reply]
