WebA well-fitting model shows no significant difference between the model and the observed data, i.e. the reported p-value should be greater than 0.05. References Hosmer, D. W., and Lemeshow, S. (2000). Applied Logistic Regression. Hoboken, NJ, USA: John Wiley and Sons, Inc. tools:::Rd_expr_doi ("10.1002/0471722146") Examples Run this code WebThe test statistic follows a Chi-squared distribution with G-2 degrees of freedom. A large value of Chi-squared (with small p-value < 0.05) indicates poor fit and small Chi-squared values (with larger p-value closer to 1) indicate a good logistic regression model fit.
