Thank you David and Jay for your help and the link. Sorry for the delay reply as I was not feeling well. the dependent variable is expressed as ratio (abnormal accrual scaled by total assets), and the MV is expressed as ratio as well (market value of assets scaled by total assets). So I think I should have said : excessively overconfident bidders have a greater incentive to manage earnings via accruals, approximately 0.0596 percent more than rational bidders for each one percent increase, for MV. I have also tried the above the average MV ( dummy = 1 if the bidder MV is higher than the industry). The coefficent for MV above the industry is -0.0592, and the interaction term for both dummies (OC*MV above industry)= 0.0782, both are significant. Will that be expressed as ratio or odds?? I will also try increase the sample size, use other proxy for MV, and apply log , poisson vce(robust) By the way the book is John Fox (1997), Applied Regression Analysis, Linear Models, and Related Methods, Sage Publications Thanks again, and please any more comments are more than welcome, Nahla On 10 May 2013 15:38, JVerkuilen (Gmail) <jvverkuilen@gmail.com> wrote: > In addition to the sage advice given already, I'll toss out: > > http://blog.stata.com/2011/08/22/use-poisson-rather-than-regress-tell-a-friend/ > > Jay > -- > JVVerkuilen, PhD > jvverkuilen@gmail.com > > "They were careless people, Tom and Daisy - they smashed up things and > creatures and then retreated back into their money of their vast > carelessness, or whatever it was that kept them together, and let > other people clean up the mess they had made." -- F.
