Nettet27. jul. 2024 · Fitting a simple linear model using sklearn. Scikit-learn is a free machine learning library for python. We can easily implement linear regression with Scikit-learn using the LinearRegression class. After creating a linear regression object, we can obtain the line that best fits our data by calling the fit method. NettetThe equation of a straight line is y = mx + b. Once you know the values of m and b, you can calculate any point on the line by plugging the y- or x-value into that equation. You can also use the TREND function. When you have only one independent x-variable, you can obtain the slope and y-intercept values directly by using the following formulas:

Nettetin linear regression we can handle outlier using below steps: Using training data find best hyperplane or line that best fit. Find points which are far away from the line or hyperplane. pointer which is very far away from hyperplane remove them considering those point as an outlier. i.e. D (train)=D (train)-outlier. NettetLinear regression fits a data model that is linear in the model coefficients. The most common type of linear regression is a least-squares fit, which can fit both lines and polynomials, among other linear models.
