Best Fit set for Jias Rockwood Sample Data The variables include in the serious and high hat fit substantiation example are both described in submit 1.5. The best fit mystify for Rockwoods 25 sampling nurture (Table 1.5) tidy sum includes variables Living cranial orbit, Bathrooms, gray-haired time ?30, and Stories. Procedure Correlation analysis (Table 1.1) was precedent performed on a full mannikin of the Rockwood sample discriminating information focalise. In the correlativityal statistics analysis, variables Living cranial orbit and Fixtures was shown to take hold the highest correlation value. After that, a regression analysis was performed. From the full role example regression analysis, variables Living Area and Bathrooms shrink down the lowest p-value of 0.002227842 and 0.00905926. Because of these findings, these variables with diametrical matching sequence were used below regression analysis. The best fit model for such sample data set was obta ined by the usage of an incremental regularity first offset with two variables with the highest correlation from the full model correlation try out (Living Area and Fixtures). After 14 trials with different variable matching, model M was discovered to be the best model since it has tot tout ensembley 4 variables and the R2 value was the highest in the 4 variables category. Because the R2 value passing between model M and L was not significant, model M was identified as the best model for this data set.

Results The regression equation resulted from Model M of the Rockwood sample set is: Appraised Value = 120 138 + 59.897 (Living Area) + 29178.22 (Bathr! ooms) -14605.753 (Old Age ?30) -25243.122 (Stories) On the Model M, variables Living Area, Bathrooms, and Stories all have plus coefficients while Old Age ?30 has a be adrift out correlation. The variables with a positive correlation coefficient affect the judge value positively while the negative correlation coefficient affects the valuate value negatively. * If Living Area increases by 1 unit, with all other variables constant, the appraise value is evaluate to...If you want to get a full essay, order it on our website: BestEssayCheap.com
