2. Consider the regression model given by: B1B2X2i+B3X3i +B4X4i+ B5X5i + Ui Y (a) Suppose that a researcher believes neither X2 nor X4 are needed to explain Y and wants to formally test this conjecture. Show how to conduct the test in each of the following steps: Describe the null and alternative hypotheses. What regressions do you need to run? What test statistic do you need to calculate? (i) (ii) (iii) 1 (iv) (v) (vi) What is the distribution of the test statistic under the null hypothesis? What is the critical value of the test statistic? What is the decision rule you would follow? (b) Suppose that the researcher tested the relevance of X2 and X4, separately, and found neither coefficients are significant. What is the implication of this result on the test result of (a)?

Q1. Consider the two different losses: (i) zero/one loss where Ai = 0 and dij = 1 and (ii) generic loss where A;i = 0 and A;j = A,. Will the discriminants under both cases be same? Justify your answer by showing all the steps involved.
I just need help on on parts H, i and J. The regression line for part G is on the first page. Thank you.
I would like to know how to determine the y and x factors needed to compute a multiple regression program based on the data supplied with this request. The solution here on Bartleby has broken images and has no assistance. I have learned how to run the program in Excel however, I am not sure which columns are needed in the analysis. The question simply states - estimate the demand for soft drinks using a multiple regression program available on your computer. Help? Thanks!
Kindly do not reject helping me with the questions. I am really having trouble understanding and I actually tried to solve by myself and I want to tally my answer. a) I fot F= 32 and p value as 0.000478. However, I am not sure how to calculate c). And I would appreciate if you solve BEING AN EXPERT and do not reject the questions.
)A county real estate appraiser wants to develop a statistical model to predict the appraised value of 3) houses in a section of the county called East Meadow. One of the many variables thought to be an important predictor of appraised value is the number of rooms in the house. Consequently, the appraiser decided to fit the simple linear regression model: E(u) = Bo + Bix, where y = appraised value of the house (in thousands of dollars) and x = number of rooms. Using data collected for a sample of n = 73 houses in Fast Meadow, the following results were obtained: y = 73.80 + 19.72x What are the properties of the least squares line, y = 73.80 + 19.72x? A) Average error of prediction is 0, and SSE is minimum. B) It will always be a statistically useful predictor of y. C) It is normal, mean 0, constant variance, and independent. D) All 73 of the sample y-values fall on the line.

(13) Assume we are interested in estimating the following regression. Y = B1 + B2x1t + B3x21 + B3X31 + uz However, we wanted to check for multicollinearity and run the below regression. X1t = a1 + azX2t + azX3; + et We find that R-Square = 0.65. Based on this we can argue that: Select one: a. VIF=1.18 and there is no multicollinearity b. VIF=2.86 and there is no multicollinearity c. VIF=12.5 and there is multicollinearity d. VIF=1.82 and there is multicollinearity
