This is the time to research how to study approximately the value of variables as lost in the analysis.Multiple linear regression estimation method proposed by the loss of 4 variables how is ratio method.1st quartile How ratio quartile 3. The regression equation method-ratio quartile 1 and equation method.Regression-ratio quartile 3. Developed from the estimated ratio comparisonThe performance of the method presented in such a way with 4 ways, with an average loss estimates and value.Mr. lash derived from regression analysis Using an estimate of the square root of the average chromatic aberration.The second position, and the average of the percentage criterion is an absolute aberration in comparison.The performance, which was to try out scenarios. When there is a normal distribution of data size.Variance percent loss, and various studies have found that the results of the regression equation method-quality ratio.Tile 1 can be highly effective in many situations than the other methods include: (1) when the sample size is small.(N = 1) the percentage loss of data (20%) of the variance of (relatively high tolerances.2 = 1.5, 2), (2) sample size is medium (n = 40, 60), minimal data loss percentage (10%)The high variability of measured tolerances ( 2 = 0.5, 1), (3) the sample size (n = 40, 60) Percentage.Data loss, medium (3%) of the variance of the medium (chromatic aberration. 2 = 1, 1.5), and(4) a large sample (n = 100) the percentage loss of data medium (15%) of the variance.Medium (chromatic aberration. 2 = 1.5) regression equation method-part ratio quartile 3 would have.Higher performance than the other way around, when the sample is large (n = 100) the percentage loss of data medium.(15%) of the variance of the medium (chromatic aberration. 2 = 1). However, the performance of.The method estimates the loss in this way, the two are not much different in all situations.
