search for: discrimint

...gs follow... I've searched R-Help, the R Website and done a GOOGLE without success for a one way ANOVA procedure to analyse data that are both non-normal in nature and which exhibit unequal variances and unequal sample sizes across the 4 treatment levels. My particular concern is to be able to discrimintate between the 4 different treatments (as per the Tukey HSD in happier times). To be precise, the data exhibit negative skew and platykurtosis and I was unable to obtain a sensible transformation to normalise them (obviously trying subtracting the value from range maximum plus one in this process)...

Hello, It might be an easy question but if you have many variables to fit in the lm function, how do you take all without specifying var1+var2+...+var2100 in the terms parameter in response ~ terms? Cheers, Carol
