Sensitivity analysis for logistic regression
WebFitting this model looks very similar to fitting a simple linear regression. Instead of lm() we use glm().The only other difference is the use of family = "binomial" which indicates that we have a two-class categorical response. Using glm() with family = "gaussian" would perform the usual linear regression.. First, we can obtain the fitted coefficients the same way we … WebJun 11, 2024 · The discriminative ability of the model was expressed as sensitivity, specificity, accuracy, and area under the curve, respectively. Results: The experimental results demonstrated that the binary logistic regression model yielded specificity, sensitivity, and accuracy of 97.3%, 98.8%, and 98.2%, respectively. Conclusion:
