Table 7 Back-fire regression model statistics from the seasonal fire intensity field study conducted in Mali, West Africa, from 2014 to 2016. F and Sig F are F-test and significance, respectively, and #χ is the number of independent variables in the model. Y = log fireline intensity; X1 = wind speed (m s−1); X2 = humidity; X3 = ambient temperature (°C); X4 = mid-season dummy variable; X5 = grass percentage of biomass; X6 = early-season dummy variable; X7 = annual and perennial binary variable
