From: Elena on 6 Aug 2010 05:23 Hi to everyone, I had to do a test of equivalence, that is: -the null hypothesis: the difference between the treatment mean and the reference mean is not near zero.In particular, the difference is less than the lower equivalence bound or greater than the upper equivalence bound and thus nonequivalent. -the alternative: the difference is between the equivalence bounds; therefore, the two means are considered to be equivalent. I'm searching for documentation about it, but I have found very few informations. Anyone could me how to do it with Sas? In particular with the use of proc glm Thank you, Elena

Proc TTEST has TOST methodology and references. Is that sufficient? |
