WebPartial answer : for a single representation, you can use the sum_of_k_squares function : sage: sum_of_k_squares(3, 12345678) (63, 147, 3510) sage: 63^2 + 147^2 + 3510^2 12345678. Finding all representations looks costly. Could you please provide an example of B and n you are willing to deal with ? WebThe SS in a 1-way ANOVA can be split up into two components, called the "sum of squares of treatments " and "sum of squares of error ", abbreviated as SST and SSE. Algebraically, this is expressed by where k is the number of treatments and the bar over the x.. denotes the "grand" or "overall" mean.
Web3 Apr 2024 · The formula for the sum of squares of the first n natural numbers is: sum_of_squares = n*(n+1)*(2n+1)/6. Using this formula can help avoid early overflow because it avoids having to square large numbers in each iteration of a loop. Instead, we can calculate the sum of squares directly using simple arithmetic operations. WebLet f(n,m) be the maximum of the sum of the squares of degrees of a graph with n vertices and m edges.
