Where PF is the reference land cover and \(x_{1}\) through \(x_{4}\) are
indicator variables for IF, YF, SC, and IP. The regression coefficients\(\alpha_{0},\alpha_{1},\text{\ α}_{2},\alpha_{3},and\ \alpha_{4}\)represent the intercepts and the coefficients\(\beta_{0},\beta_{1},\text{\ β}_{2},\beta_{3},and\ \beta_{4}\) are the
slopes.
ANCOVA was used to compare the following model, equation 2 (Schneider et
