What to Focus On
- Regression analysis studies the relationship between dependent and independent variables.
- It was developed by Sir Francis Galton in 1877.
- The dependent variable y is the variable being forecast.
- Regression finds a mapping from x to continuous y.
- Data collection and cleaning are important.
- Graphs help check the type of relationship.
- Simple linear regression uses one independent variable.
- Multiple linear regression uses multiple independent variables.
- Polynomial regression models curved relationships.
Common Mistakes to Avoid
Regression can be used for any type of dependent variable, including categorical data.
The independent variable is always continuous, so categorical inputs cannot be used in regression.
Simple linear regression and multiple linear regression are the same thing, just written with different symbols.
