Maarten, I kind of disagree back - from a specific angle... The odds ratio is something I personally -and others- have difficulty grasping, in terms of its natural meaning. Risk ratios/ratios of probabilities on the contrary are considerably easier to get... Under known circumstances odds ratios and risk ratios are numerically very similar ... all too often they are not... and then this misinterpretation bites... I think that this is what Steven meant... tom On Jan 13, 2008 1:04 PM, Maarten buis <[email protected]> wrote: > --- Steven Samuels <[email protected]> wrote: > > A linear probability model is desirable because effects are risk > > differences, which are much easier to interpret than odds ratios. > > I disagree, both measures are perfectly understandable.
