Michael G. Rupert, Susan H. Cannon, Joseph E. Gartner
2003, Open-File Report 2003-500
Logistic regression was used to predict the probability of debris flows occurring in areas recently burned by wildland fires. Multiple logistic regression is conceptually similar to multiple linear regression because statistical relations between one dependent variable and several independent variables are evaluated. In logistic regression, however, the dependent variable is...
