Table 3 Coefficient estimates of regressions (from Eqs. 13: α1, α2, etc., are the covariate coefficients corresponding to x1, x2, etc.; μ is the intercept; and σ is the scale); coefficient standard error estimate in parentheses. Variable codes are: diameter at breast height (DBH; cm); crown injury percent (CI); and years to mortality post fire (YTD) by species and status. Species codes are: IC = incense-cedar; SP = sugar pine; WF = white fir; and YP = yellow pine. Superscript numbers indicate model-averaged variable importance rank. ∆AIC is the difference between this model and the best AIC model. Those terms that are less than 0.8 in model-averaged importance are noted with an asterisk (*)
