Solved Problem Given The Following Table Of Values Xi Yi Chegg Instant answer step 1 2 (a) to find the estimated regression line, we need to calculate the slope and intercept coefficients, βˆ 0 and βˆ 1, respectively. we can use the formula: βˆ 1 = ∑ (xi x̄) (yi ȳ) ∑ (xi x̄)² where x̄ and ȳ are the sample means of xi and yi, respectively. The slope of the best fit regression line can be found using the formula. c1 = n (∑xy)−∑x ∑y n (∑x 2)− (∑x) 2 the y intercept of the best fit regression line can be found using the formula. c0= (∑y) (∑x 2)−∑x ∑xy n (∑x 2) − (∑x) 2 n=4 sum up the x values. Solution: the implementation in r (see appendix) and graphs are attached. it's clear that for k = 1; 3; 5; 7 and 15, the k nearest neighbor has a smaller classi cation error for the testing dataset compared to that of the linear regression. Question: consider the following observed values of (xi , yi): (1, 2) (2, 4) (3, 5) (4, 4) (4, 8) (5, 7) (a) find the estimated regression line yˆi = βˆ 0 βˆ 1xi based on the observed data.

To demonstrate the linearity for the estimator in this regression model, we will use the sixth a assumption of the ols, that is, the values of the independent variable are the same for all hypothetical samples. We break down yi into two components, the deterministic (nonrandom) com ponent β1 β2xi and the stochastic (random) component ui. the explanatory vari able is xi and the population parameters we want to estimate are given by intercept β1 and the slope β2. For each xi, compute the fitted value of yi using ŷ= bo bixi. c. compute the residuals, e; = yi yi. d. find r squared (the coefficient of determination). (a) (b) (c) your solution’s ready to go! our expert help has broken down your problem into an easy to learn solution you can count on. We may calculate the mle for a by taking the mean of these values and dividing it by the total number of observed y values. the slope of the regression line that connects ln (y) and xi is the estimate for b that has the highest possibility of being correct.
