Explanation (R2) of fire behavior variation and relative importance (fi, standardized regression coefficients) of the independent variables.

Fire variable R2 Independent variables (p < 0.05), β
Rate of spread 0.89 WAF, 0.62 Fuel depth, 0.34 Md, –0.26
Fireline intensity 0.85 Fuel load, 0.94 Rate of spread, 0.85
Crowning potential 0.88 Crown base height, –0.59 Fireline intensity, 0.45

Md = moisture content of fine dead fuel.
