Classification Accuracy,Confusion matrix, AUC and ROC

we already discussed how to calculate accuracy for linear regression with the help of R-Square, Adjusted R-Square, MSE etc..Can we use the same mechanism to calculate the accuracy for classification problem? Simple answer is NO, we have different mechanism to calculate accuracy for classification problems. Classification Accuracy: It is very simple to calculate, number ofContinue reading “Classification Accuracy,Confusion matrix, AUC and ROC”

Calculating Accuracy

In our previous article we seen how to calculate linear regression by hand, in this article we will discuss how to find the accuracy of our linear regression model which we build. Below are the metrics we need to calculate to check our model accuracy. R^2 (Coefficient of Determination) Adjusted R^2 MSE RMSE First,Continue reading “Calculating Accuracy”
