(1) not shown because of not having any meaningful interpretation (2) all covariates were z-transformed to a mean = 0 and sd = 1, original means (sd) were: curvature: 175.67(10.61); epa: 68.46(14.90); thickness evenness: 2.71 (2.18); platform depth: 10.53(6.82) (3) square root transformed prior to z-transformation (4) standardized by the geometric mean The results of the reduced Generalized Linear Model, with no interactions.
