According to this post in Wikipedia the residual sum of squares (RSS), the sum of squared residuals (SSR) and the sum of squared errors of prediction (SSE) are the same.
So the RSS = SSR = SSE
Now, according to this post in Wikipedia the explained sum of squares (ESS), is the same as the model sum of squares (SSR) but the residual sum of squares (RSS) is not the same as the SSR
So here the ESS = SSR ≠ RSS?
