Regression Paper - Essay Example Moreover, if the significance level is very small, practically less than 0.05, then, it means that the correlation is significant at the same time the two variables are linearly related. However, if the significance level is moderately large, then the correlation is insignificant and these two variables are not linearly related. The t statistics will determine the relative significance of each variable in the model. As a guide on the useful predictors, note for t values well, -2 or above +2. R squared is defined as the variation's proportion in the dependent variable and explained by the regression model. R square values range from 0 to 1. The correlations table presents Pearson correlation coefficients, the significance values, as well as the number of cases containing non-missing values. Clearly, Pearson correlation coefficients presume that data are normally distributed. Values of the correlation coefficient are in the array from -1 to 1. Subsequently, the sign we can see in the correlation coefficient designates the direction of the relationship (+ or -). The fixed value shown by correlation coefficient indicates the strength, if the absolute values are larger it means, it has stronger relationships. Moreover, if the significance level is very small, practically less than 0.05, then, it means that the correlation is significant at the same time the two variables are linearly related. However, if the significance level is moderately large, then the correlation is insignificant and these two variables are
