Comparing the shapes of regression functions

WebJan 28, 2024 · Like individual value plots, use boxplots to compare the shapes of distributions, find central tendencies, assess variability, and identify outliers. Boxplots are also known as box and whisker plots. While boxplots have the same goals as individual value plots, they look very different. Boxplots graphically display the five-number summary. WebFeb 9, 2024 · A regression equation is a polynomial regression equation if the power of independent variable is more than 1. The equation below represents a polynomial equation: y=a+b*x^2. In this regression technique, the best fit line is not a straight line. It is rather a curve that fits into the data points. Important Points:

WebThe cost function for both ridge and lasso regression are similar. However, ridge regression takes the square of the coefficients and lasso takes the magnitude. Lasso regression can be used for automatic feature selection, as the geometry of its constrained region allows coefficient values to inert to zero.
