Hi everyone, I intend to do a discriminant analyse for 2 measures(eye diameter and body length) and for different areas to show differences between those areas if there are any. The raw data (eye diameter, body length) make one cloud of points so it seems there aren't any differences between those areas. If I take the mean values (eye diameter) for length classes, I nearly get linear functions that differ in slope and intercept. The question is: Can I do something like a discriminant analyse for those lines to statistically separate them from each other or is there a totally different method for this case. If you know any method, please, could you let me know. Thanks, Ben --
Hello everybody, I would like to carry out a discriminant analyse.I have two variables: eye diameter and body length. I have values for different areas and would like to separate those areas from each other according to the variables. Taking the raw data returns a cloud of points.The areas don't seem to differ;so I made length groups and took the mean eye diameter for each length group.I roughly got linear functions. The question is: Can I carry out something like a discriminant analyse for those lines,too? Or does anyone know other statistical methods for separating those areas? (the data aren't unfortunately normally distributed, so an ANOVA shouldn't be the right way). Many thanks, Ben --
