Notice how the squaring process in the sum of squares formula ensures that it tends to increase with each additional data point. Negative differences are squared, producing a positive value that adds to the total. Only the rare observations that equal the mean exactly contribute zero to the sum...
The sum of squares can also be used to calculate other statistical measures, such as thecoefficient of determinationand themean squared error. References Statistical Measures of Dispersion 13.2 – The ANOVA Table Measures of Variation
It calculates the squared difference of each data point in a data set, and then takes the sum of each of these points. What does the sum of squares tell you? The sum of squares explain the amount of variation in that specific data set. On its own it can't be used to compare to ...

On another sheet in the sample file, there is a list of Summary functions, and a formula that looks up the numeric value for each function. The cell with the formula is namedFuncSelCode. When the FuncSel cell is changed, the Worksheet_Change code on that sheet runs. ...
The cross-validated predictive performance was then evaluated by minimizing the root mean squared error (RMSE) or maximizing the Pearson correlation to rank the predictive capability of individual pathways. When this analysis was applied to the CTD2 dataset24,“REACTOME_POST_TRANSLATIONAL_PROTEIN_...

The RSS measures the amount of error remaining between the regression function and the data set after the model has been run. A smaller RSS figure represents a regression function that is well-fit to the data. The RSS, also known as the sum of squared residuals, essentially determines how ...
The sum of squares measures how widely a set of datapoints is spread out from themean. It is also known as variation. It is calculated by adding together the squared differences of each data point. To determine the sum of squares, square the distance between each data point and the line ...
