| Abstract | ||
| In many regression studies , there is an ambition to compare the relative importance of the explanatory variables where there are different measures that can be used : t values , regression coefficient , p values , and the frequently used is standardized regression coefficients (beta coefficients). It is can be calculated in two ways , with both leading to the same result ,therefore , it is often difficult to say which of the explanatory variables is most important in determining the value of the dependent variable , since the value of the regression coefficients depends on the choice of units to measure X. The research is dealing to calculate partial standard deviation when the joint distribution is unknown , also the research explain the relationship between the new coefficients will be similar to comparing values, and the important part is to explain the one weakness of the standardized coefficients when the coefficients are used . As the partial (applied ) side of the this research has conserving the special data of the Stock market , the price per share Y , two variables that are thought to influence stock price average equity , and annual rate of dividend . a statistical programmed is here used that is (SPSS,) for the analysis of the data. | ||
