Question

Any stats guys can help me with this question please!! Thank you!

With calculation will be appreciated!!

The following is the Correlation and Regression output from a Multiple Regression run in Excel. The dependent variable is "Median Home Value" (MEDHOMEVALD. The other variables are the Independent variables: "Robbery rate" (ROBBERY "%Working outside county of residence" (WORKOUTSIDE), ROWHOUSE with 5 or more units" (5+ UNITS), of Housing very Crowded" (1.5 PER RM), & Houses that use LP Gas" LP GAS). Please answer the following questions: a. Which variables pass the "P-Value test"? b. Which variable pairs are "multicollinear"? c. Compute the Coefficient of determination (R-Square) for each independent variable. d. Write out the complete regression equation. MEDHOMEVAL ROBBERY WORKOUTSIDE Row HOUSE 5+ UNITS 1.5 PER RM LP GAS MEDHOMEVAL 1 ROBBERY 0.254 WORK OUTSIDE 0.235 1 -0.043 1 -0.090 ROW HOUSE 0.377 0.705 5+ UNITS 0.648 0.725 0.004 0.619 1.5 PER RM 0.652 0.431 0.057 0.314 0.658 1 LP GAS -0.617 -0.374 0.041 -0.413 -0.509 -0.404

Explanation / Answer

Answers

a. The variables Robbery rate, %working outside country of residence, % with 5 or more units, % of housing very crowded, % houses that use LP Gas pass the P-value test because the p-values associated with these variables are significant at significance level 0.05.

b. Robbery rate and ROWHOUSE (%) are multicollinear as there is strong correlation exists between these two variables.

Robbery rate and % with 5 or more units are multicollinear as there is strong correlation exists between these two variables.

c.

Robbery rate

Coefficient of determination, R2 = (0.254)2 = 0.065

%working outside country of residence

Coefficient of determination, R2 = (0.235)2 = 0.055

ROWHOUSE (%)

Coefficient of determination, R2 = (0.377)2 = 0.142

% with 5 or more units

Coefficient of determination, R2 = (0.648)2 = 0.420

% of housing very crowded

Coefficient of determination, R2 = (0.652)2 = 0.425

% houses that use LP Gas pass

Coefficient of determination, R2 = (-0.617)2 = 0.381

d. The estimated regression equation is given by,

Median Home Value = 81789.73 – 217.82 * Robbery rate + 865.87 * %working outside country of residence + 167081.38 * ROWHOUSE (%) + 268303.46 * % with 5 or more units + 715776.56 * % of housing very crowded – 276214.97 * % houses that use LP Gas pass
