Instead it is the cumulative sum of differences between the values and the average. Because the average is subtracted from each value, the cumulative sum also ends at zero. If S(i) is positive or negative for more than a few points in a row it is an indication there may be a change in the process.

The line minimizes the sum of squared differences between observed values (the . y. values) and predicted values (the ŷ values computed from the regression equation). The regression line passes through the mean of the . X. values (x) and the mean of the . Y. values (y). The regression constant (b0) is equal to the . y intercept. of the ...

The Sums of Squares: 1) Computing SStotal: The SStotal is the SS based on the entire set of scores in the study.So computing this SS is the same as if you just stacked your different treatment samples together to form a single sample and then computed the Sum of Squares on that one larger sample.

A. Use your calculator. B Since it follows the standard normal distribution, the standard deviation(s) equals to one. S= variance = 1. A. Z= (42-50)/10=-0.8. Enter table A under Z=-0.8. The table entry is 0.2119. This is the area to the left of –0.8. Because the total area under the curve is 1, the area lying to the right of –0.8 is 1-0 ...

The corrected sum of squares (CSS) is calculated as the sum of the squared distance from each treatment mean to the grand-mean. For example, there are two treatments with mean of 10 and 20, respectively. That gives us a grand mean of (10+20)/2=15 (assuming equal cell size). Therefore, the corrected sum of squares is: (10-15)2+(20-15)2=50.

The average return is subtracted from each single period return; this difference is then squared. The squared differences are summed. This sum is divided by the number of periods (using population data) or the number of periods minus 1 (using sample data). Year Rt (Rt – E(R))2 (Rt – E(R))2
