- In python, for a sample data with 4 columns and 60 rows how do you find the parameters for the regression with the feature map (see attached) where we consider the loss function to be the square of residuals. Once this is done, how do you compute the empirical risk? I've attached some of the data below, it would be sufficient to see how you get results for the question using the above dataset. 1 14 25 620 -1 69 29 625 0 83 27 850 0 28 25 1315 1 41 25 2120 -1 153 31 1315 0 55 25 2600 0 55 31 490 1 69 25 3110 1 83 25 3535Find out other univariant linear regression models and compare between themThe advantages of transitioning from stepwise regression to all-subsets regression are described in detail below.

Give an example of each and illustrate them graphically.Develop a simple linear regression model (univariate model) using gradient descent methodfor experience-salary datasets as it is shown on the following table. Once you got the model, checkhow close the predicted values against the ground truth and calculate the total error (mean squareerror) and the accuracy R2.

Group of answer choices True FalseQuestion 1: In class we went over the derivation for linear regression on the white board. Starting with = the step where you have E (Y – XW)¹ (Y – XW) write the derivation to get to the step W = (XTX)-¹XTY. Explain the math used in each step.Below is a detailed discussion of the advantages of all-subsets regression versus stepwise regression.
