Today’s lecture was about some equations and few regression concepts.
- Correlation between predictor and variables
2. Interaction Term
3. Generalized Linear Mode
4. Overfitting = In this, data fits in the model so well but it does not predicts anything.
5. Method to check overfitting = Cross-validation.
Work on project…
- Extract the data from the given pdf.
- Checked first few figures for reference by using (.head).
- Checked the shape of the dataset (df.shape).
- Get description of the dataset where I got to know Count, Mean, Max, Min, Std, and percentage wise distribution (df.describe()).
- Checked data types (df.types).
- Checked if there is any null value (df.isnull.sum()).
