Negative binomial regression was more effective to handle the over dispersion that causes bias in parameter estimations in Poison regression. The generalized estimating equations were used for analyzing repeated categorical data. GEE estimates were obtained by using the exchangeable working correlation. As a result of GEE analyses, it was concluded that flehmen lip curl response, tail raising, mount duration, vocalization and weight of the ram lamb were statistically important (p<0.05) for mount frequent. However, the anogenital sniff found be not significant.]]>Agresti, A.,1997Breslow, N.,199085565571Cameron, A.C. and P.K. Trivedi,19982nd Edn.,Cox, R.,198370269274Dalrymple, M.L., I.L.
