Regression involves predicting a continuous outcome based on input features. Here are 100 tips for working with linear regression:
1. Basics of Linear Regression:
- Understand the basic concept of linear regression: modeling the relationship between a dependent variable and one or more independent variables.
- Familiarize yourself with the linear regression equation: y=mx+b, where y is the dependent variable, x is the independent variable, m is the slope, and b is the intercept.
2. Data Preparation:
- Ensure that the assumptions of linear regression are met: linearity, independence, homoscedasticity, and normality of residuals.
- Handle missing data appropriately, considering imputation or removal of missing values.
3. Exploratory Data Analysis:
- Visualize the relationship between the independent and dependent variables using scatter plots.
- Check for outliers and influential data points that might affect the regression model.
