temperature=m*age+cAnd need to find the values of m and c during the fitting procedure. If we found m = 0.5 and c = 37, we might visualize it like this:This would mean that every year of age is associated with body temperature increase of 0.5°C, with a starting point of 37°C...
Mean Squared Error (MSE): MSE measures the average squared difference between the predicted values and the actual values of the dependent variable. It provides an overall assessment of the model’s prediction accuracy, with lower values indicating better performance. However, MSE is sensitive to out...
