- What is the significance of R and R2 in gression model?arrow_forwardThe lines of regression of y on x and x on y are, respectively, y = x + 5 and 16x - 9y = 94. Find the variance of x if the variance of y is 16. Also, find the covariance of x and yarrow_forwardIn the least-squares regression model, y, = B, X; + Bo +&, &, is a random error term with mean and standard deviation og In the least-squares regression model, y, = B4 X; + Bo + E, ɛ, is a random error term with mean V and standard deviation oarrow_forward
- Consider the points (1, 1), (2, 3), (−3, 1). Find the least squares regression line.arrow_forwardAn owner of a home in the Midwest installed solar panels to reduce heating costs. After installing the solar panels, he measured the amount of natural gas used y (in cubic feet) to heat the home and outside temperature x (in degree-days, where a day's degree-days are the number of degrees its average temperature falls below 65° F) over a 23-month period. He then computed the least-squares regression line for predicting y from x and found it to be ŷ = 85 + 16x. The software used to compute the least-squares regression line for the equation above says that r2 = 0.98. This suggests which of the following? 1. Gas used increases by square root of 0.98 = 0.99 cubic feet for each additional degree-day? 2. Although degree-days and gas used are correlated, degree-days do not predict gas used very accurately. 3. Prediction of gas used from degree-days will be quite accurate.arrow_forwardIn a typical multiple linear regression model where x1 and x2 are non-random regressors, the expected value of the response variable y given x1 and x2 is denoted by E(y | 2,, X2). Build a multiple linear regression model for E (y | *,, *2) such that the value of E(y | x1, X2) may change as the value of x2 changes but the change in the value of E(y | X1, X2) may differ in the value of x1 . How can such a potential difference be tested and estimated statistically?arrow_forward
- Use the general equation for the least square regression line to show that this line always passes through the point (x,y) * bars above the x and y.That is, set x=x(with a bar above the x) and show that the line predicts that y=y (with a bar above the y).arrow_forwardFind the least-squares regression line ŷ = bo + bjx through the points (-2, 0), (3, 7), (5, 14), (9, 19), (12, 26), and then use it to find point estimates ŷ corresponding to x = 4 and x = 10. For x = 4, y = For x = 10, y =arrow_forwardBased on a sample on n observations, (x1, y1 ), (x2, y2 ), c, (xn, yn), the sample regression of y on x is calculated. Show that the sample regression line passes through the point (x = x̄, y = ȳ), where x̄ and ȳ are the sample means.arrow_forward
