I posted this question in a previous message which must have been too long to wade through.
So here is the question only, the data description omitted: Is there a particular model (or correction) I can use for two way (fixed factors) analysis of variance (ANOVA) when the sizes of treatment groups are not equal----variance heterogeneity is established by Levene's and Bartlett's test----and when some of the row-column interactions have zero size (n=0)? . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
