test was used for the random effect (Family). Denominator degrees of freedom
for the univariate fixed effects ranges from 116 to 121 and were determined
by the Satterthwaite approximation.Appendix G. Multivatiate analyses
followed by mixed-model univariate analyses for effects of grass competition,
root herbivory by beetles, and full sibling family of milkweed on the natural
log of final fruit production, mass per fruit, and vegetative biomass at the
end of the second growing season. The likelihood-ratio
test was used for the random effect (Family). Denominator degrees of freedom
for the univariate fixed effects ranges from 116 to 121 and were determined
by the Satterthwaite approximation.
