I have a 2x3 table and want to see the association between two variables. I compiled the data and inputed it into SAS and attempted to use Two-Way Anova for comparison. All is going according to plan but when i ran the interaction from proc glm for two variables, SAS was unable to give me a p-value and it was left blank. If I to understand this as meaning the p-value is so tiny, it is nonexistant?</P><P></P><P>Pengy</P></BODY></HTML> Mon, 24 Nov 2014 20:35:48 GMT https://communities.sas.com/t5/SAS-Procedures/Two-Way-Anova-not-displaying-p-value/m-p/184780#M46966 RCPenguin 2014-11-24T20:35:48Z Re: Two-Way Anova not displaying p-value https://communities.sas.com/t5/SAS-Procedures/Two-Way-Anova-not-displaying-p-value/m-p/184781#M46967 <HTML><HEAD></HEAD><BODY><P>You say 2x3 table but then Anova which makes me wonder.
