Its worst-case roundoff errors grow asymptotically as at most O(ε log n), where ε is the machine precision (assuming a fixed condition number, as discussed below). [1] In comparison, the naive technique of accumulating the sum in sequence (adding each x i one at a time for i = 1, ..., n) has roundoff errors that grow at worst as O(εn). [1]
A contrast is defined as the sum of each group mean multiplied by a coefficient for each group (i.e., a signed number, c j). [10] In equation form, = ¯ + ¯ + + ¯ ¯, where L is the weighted sum of group means, the c j coefficients represent the assigned weights of the means (these must sum to 0 for orthogonal contrasts), and ¯ j represents the group means. [8]
In order for the paper to meet back up with itself at the final angle, Kawasaki's condition must be met. [3] [4] [7] [8] Showing that the condition is also a sufficient condition is a matter of describing how to fold a given crease pattern so that it folds flat. That is, one must show how to choose whether to make mountain or valley folds, and ...
The algorithm performs summation with two accumulators: sum holds the sum, and c accumulates the parts not assimilated into sum, to nudge the low-order part of sum the next time around. Thus the summation proceeds with "guard digits" in c , which is better than not having any, but is not as good as performing the calculations with double the ...

December 26, 2024 at 8:59 PM Texas Game Warden SHERMAN – Thursday marked Day 3 in the Texas search for an 8-year-old Oklahoma girl missing since she was swept away in raging waters on Christmas Eve.
30 samples of 10 dots of random color (blue or red) are observed. On each sample, a two-tailed binomial test of the null hypothesis that blue and red are equally probable is performed. The first row shows the possible p-values as a function of the number of blue and red dots in the sample.
