its characteristics. A 95% confidence level was chosen and a prediction interval which is a confidence interval estimate of a predicted value of the selling price used. The MegaStat output of a Regression Analysis of the Bryant/Smith Case 28 data was used as the basis to calculate the multiple regression equation as the prediction point. The point prediction of the selling price of a house corresponding to the combination of values of the independent variables is; Y = -12.5988 + 0.0383(X1) + 4.3573(X2)

which included income‚ education and age‚ to determine the effectiveness of the framework provided. These tests were constructed using regression techniques and empirical data from the American Community Survey to see if a positive correlation exists between the three independent variables and mate selection at the time of marriage. The results from the regression models of income‚ education and age reveal that these preferences play a predominant part of choosing a soul mate‚ further indicating that

since the last tank fill up‚ the number of people living in the home‚ and a home index that measures the energy efficiency of the homes. The results of the linear regression models that were tested showed that degree days and the home index were significant predictors of heating oil usage. Based on the results of the linear regression analysis‚ a forecast was created to predict the amount of heating oil customers would use based on an average home index.

covariates significantly associated (P < .05) with exposure to rap music videos in bivariate analyses were included in logistic regression analyses. A separate logistic regression analysis was conducted to examine the relation between level of exposure to rap music videos at baseline and the occurrence of each health risk behavior over the 12-month follow-up. All logistic regression analyses controlled for covariates and the

1. What is the difference between R2 and adjusted R2? R2 is a statistic that will give some information about the goodness of fit of a model. In regression‚ the R2 coefficient of determination is a statistical measure of how well the regression line approximates the real data points. An R2 of 1.0 indicates that the regression line perfectly fits the data. Adjusted R2 is a modification of R2 that adjusts for the number of explanatory terms in a model. Unlike R2‚ the adjusted R2 increases only if

Abstract In the experiment the reduction of Cr(VI) by glutathione will be monitored‚ the data will be recorded and the double-exponential dependence of the reaction will be analyzed. Exponential stripping‚ as well as computer assisted non-linear regression analysis will be utilized to determine the rate equation as well as the rate constants of the reaction. Introduction Many biochemical reactions and their rates cannot be simply described by basic kinetics such as first or second order.1 Many are
