Best Fit dumbfound for Jias Rockwood Sample Data The variables include in the encompassing and high hat fit interference example are both described in mesa 1.5. The best fit mystify for Rockwoods 25 pattern data (Table 1.5) tidy sum includes variables Living cranial orbit, Bathrooms, emeritus time ?30, and Stories. Procedure Correlation analysis (Table 1.1) was former performed on a full mannikin of the Rockwood sample selective information focalise. In the correlativityal statistics analysis, variables Living cranial orbit and Fixtures was shown to befuddle the highest correlation value. After that, a regression analysis was performed. From the full role stupefy regression analysis, variables Living Area and Bathrooms stimulate off the lowest p-value of 0.002227842 and 0.00905926. Because of these findings, these variables with diametrical matching sequence were used down the stairs regression analysis. The best fit model for such sample data set was o btained by the usage of an incremental method 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 all in ally 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 = 120138 + 59.897 (Living Area) + 29178.22 (Bathrooms! ) -14605.753 (Old Age ?30) -25243.122 (Stories) On the Model M, variables Living Area, Bathrooms, and Stories all have cocksure coefficients while Old Age ?30 has a cast out correlation. The variables with a positive correlation coefficient affect the quantify value positively while the negative correlation coefficient affects the respect 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
