The Calculation Of The Coefficient Of Determination Depends On The Number Of Independent Variables An Adjusted Value Of 2 (25.53 KiB) Viewed 104 times
The calculation of the coefficient of determination depends on the number of independent variables. An adjusted value of ² based on the number of degrees of freedom is calculated using the formula shown below, where n is the number of data pairs and k is the number of independent variables. [(1-²)(n-1)] n-k-1 adj Data were found on eight pre-owned sedans of a certain make Suppose a multiple regression on these data has 4 independent variables. The coefficient of determination is found to be 0.916 based on a sample of 15 paired observations. After calculating rad determine the percentage of the variation in y that can be explained by the relationships between variables according to Compare this result with the one obtained using ² adj ady = 0 (Round to three decimal places as needed.)
