There are many types of regressions such as ‘Linear Regression’, ‘Polynomial Regression’, ‘Logistic regression’ and others but in this blog, we are going to study “Linear Regression” and “Polynomial Regression”. In this example we will apply linear regression as well as polynomial regression on the same dataset and will see the results of both the models. #importing the libraries import numpy as np import pandas as pd import matplotlib.pyplot as plt %matplotlib inline We see that both temperature and temperature squared are significant predictors for the quadratic model (with p -values of 0.0009 and 0.0006, respectively) and that the fit is much better than for the linear fit. From this output, we see the estimated regression equation is y i = 7.960 − 0.1537 x i + 0.001076 x i 2.

This type of regression takes the form: Y = β 0 + β 1 X + β 2 X 2 + … + β h X h + ε. where h is the “degree” of the polynomial. This tutorial provides a step-by-step example of how to perform polynomial regression in R. the techniques for fitting linear regression model can be used for fitting the polynomial regression model. For example: 2 yxx 01 2 or 2 E()yxx 01 2 is a polynomial regression model in one variable and is called a second-order model or quadratic model. Figure 1 – Data for polynomial regression in Example 1 We next create the table on the right in Figure 1 from this data, adding a second independent variable (MonSq) which is equal to the square of the month.

Polynomial regression models y = Xβ + is a general linear regression model for fitting any relationship that is linear in the unknown parameters, β. For example, the following polynomial y = β 0 +β 1x 1 +β 2x 2 1 +β 3x 3 1 +β 4x 2 +β 5x 2 2 + is a linear regression model because y is a linear function of β. BIOST 515, Lecture 10 1
