Question

1. A simple (n=1) Linear Regression problem has the training data given below: | x | y | |---|---| | 4 | 2 | | 7 | 10 | | 9 | 5 | Find the following: (i) The optimal Linear Regression parameters ?? = (???, ???). (ii) The total sum of squares (TSS) and Residual Sum of Squares (RSS). (iii) The residual standard error (RSE). (iii) The observed standard errors S?E(???) and S?E(???). Use the RSE as estimator for the noise standard deviation. (v) The coefficient of determination R². (vi) The F-ratio.

Step 1

First, we need to find the optimal Linear Regression parameters (0o, 01). To do this, we need to calculate the mean of x and y values, the slope (01), and the intercept (0o). x = [2, 7, 9] y = [4, 5, 10] Mean of x: $\bar{x} = \frac{2+7+9}{3} = \frac{18}{3} = Show more…
