Hi there. Does anybody here happen to know how to perform linear regression?
As in, I've got a list of data points that ought to lie in a nearly
perfect straight line, and I want to discover what the slope and
intercept of that line is. (But each individual point might contain a
certain amount of measurement error.)
I've had a look on Wikipedia, but it starts talking about chi-squared
and Student t-distributions and covariance and basically I have no clue
what the hell any of it means. :-/
