What I think of as "regression through the origin" is hardly ever useful for anything, especially, statistical testing. What was this referring to? On the other hand, A linear trend is a compact "summary measure"; and so is the Endpoint; and the Regressed change score (from covariance) -- I thought that was where I was. > coefficients, or generalized estimating equations. > > SR Millis [ snip, previous posts] I imagine those as giving *tests* more readily than they give estimates of effects. But I haven't been using them. -- Rich Ulrich, [EMAIL PROTECTED] http://www.pitt.edu/~wpilib/index.html "Taxes are the price we pay for civilization." . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
