4 Answers. Sorted by: 1. According to your question, you can declare a function is_square (n) to check a number whether perfect square or not. Then, you take a number (i.e. val) from list l using this for val in l:. If number (i.e. val) is perfect square then it will add to the sm otherwise not. You code will be like following code : l = [1,4,9]Add the squares of errors together. The final step is to find the sum of the values in the third column. The desired result is the SSE, or the sum of squared errors. [6] For this data set, the SSE is calculated by adding together the ten values in the third column: S S E = 6.921 {\displaystyle SSE=6.921} Method 2. Essentially, the total sum of squares quantifies the total variation in a sample. It can be determined using the following formula: Where: y i – the value in a sample; ȳ – the mean value of a sample; 2. Regression sum of squares (also known as the sum of squares due to regression or explained sum of squares) $\begingroup$ Note that your first bulleted statement is not quite right, since $2$ is certainly a sum of squares, but doesn’t fall into your form. As to your last question, surely since you can express $13$ as a sum of squares, you can get the corresponding sum for $13m^2$. $\endgroup$ –Also presented as. The Sum of Sequence of Squares can also be presented as: ∀n ∈ N: n ∑ i = 0i2 = n(n + 1)(2n + 1) 6. This is seen to be equivalent to the given form by the fact that the first term evaluates to 0(0 + 1)(2 × 0 + 1) 6 which is zero .
