Test assumption of Regression Model in Data Science

70.8k

  • Linear Relationship.
  • Independence.
  • Homoscedasticity.
  • Normality.

Plotting the predicted values against the real values in the holdout set is the best way to examine regression data. In ideal circumstances, the points should lie on a 45-degree line going through the origin (y = x is the equation). The better the regression, the closer the points are to this line.

Bring up your data in SPSS and select Analyze –> Regression –> Linear to thoroughly test the regression assumptions using a normal P-P plot, a scatterplot of the residuals, and VIF values.

The content and teaching style is excellent. But there is slight issue is that video quality is kind of poor the dashboard is blur on 720mp on PC.
