I’m doing some analysis of ANCOVA, but I don’t know if I’m not able to interpret the results. I understand that an ANCOVA would be an ANOVA along with regressions. But I need a test for homogeneity of curves.
The functions Anova and aov do not return me this information, someone knows what I could do. I searched the other questions posted on the forum, but found nothing resolutive!
thank you !
After researching better about ANCOVA, it is possible to do it by R yes! Just perform an ANOVA and a homogeneity test of the slope of the curves.
