Thus, an array of numbers with 5 rows and 4 columns, hence 20 elements, is said to have dimension 2 in computing contexts, but represents a matrix that is said to be 4×5-dimensional. Also, the computer science meaning of "rank" conflicts with the notion of tensor rank, which is a generalization of the linear algebra concept of rank of a matrix.)
In this case, the winsorized mean can equivalently be expressed as a weighted average of the 5th percentile, the truncated mean, and the 95th percentile (for this case of a 10% winsorized mean: 0.05 times the 5th percentile, 0.9 times the 10% trimmed mean, and 0.05 times the 95th percentile). However, in general, winsorized statistics need not ...
Thus, if a two-dimensional array has rows and columns indexed from 1 to 10 and 1 to 20, respectively, then replacing B by B + c 1 − 3c 2 will cause them to be renumbered from 0 through 9 and 4 through 23, respectively. Taking advantage of this feature, some languages (like FORTRAN 77) specify that array indices begin at 1, as in mathematical ...
From February 2010 to December 2012, if you bought shares in companies when W. Craig Jelinek joined the board, and sold them when he left, you would have a 70.5 percent return on your investment, compared to a 30.9 percent return from the S&P 500.
A pivot position in a matrix, A, is a position in the matrix that corresponds to a row–leading 1 in the reduced row echelon form of A. Since the reduced row echelon form of A is unique, the pivot positions are uniquely determined and do not depend on whether or not row interchanges are performed in the reduction process.
Tim Hardaway Jr. hit three 3-pointers in overtime to help the Detroit Pistons end the Miami Heat’s four-game winning streak with a 125-124 victory on Monday night. Cade Cunningham had 20 points ...
1. Justin Baldoni's New York Times lawsuit could hinge on an emoji. The "It Ends With Us" director accused the paper of taking his publicists' quotes out of context.
From April 2012 to December 2012, if you bought shares in companies when Timothy C. Collins joined the board, and sold them when he left, you would have a 12.8 percent return on your investment, compared to a 2.5 percent return from the S&P 500.
