WebTo find SSres, we need to subtract the sum of squared errors (SSE) from the total sum of squares (SST): SST = n * var (y) SSE = sum (y - yhat)^2. Where y is the observed values and yhat is the predicted values. Now, let's use the given information to find the RMSE: Variance of the dependent variable = 21.9545. Multiple R-squared = 0.5514. dara torres factsWebSSE is the sum of squared error, SSR is the sum of squared regression, SST is the sum of squared total, n is the number of observations, and p is the number of regression coefficients.
