Why do we want assumptions ?
Assumptions are situations that have to be met earlier than utilizing a linear regression mannequin to make predictions or draw inferences. These assumptions are vital as a result of if they aren’t met, the mannequin’s accuracy can be considerably diminished.
- Linearity : The connection between the dependent and impartial variable must be linear.
2. Independence : The observations X1,X2,X3 are impartial of one another.
3. Homoscedasticity : The variance of the errors is fixed throughout all ranges of the impartial variable.
4. Normality : The errors observe a standard distribution.
5. No Multicollinearity : The impartial variables should not extremely correlated with one another.
