A Data Matrix on a Mini PCI card, encoding the serial number 15C06E115AZC72983004. The most popular application for Data Matrix is marking small items, due to the code's ability to encode fifty characters in a symbol that is readable at 2 or 3 mm 2 (0.003 or 0.005 sq in) and the fact that the code can be read with only a 20% contrast ratio.

The design matrix has dimension n-by-p, where n is the number of samples observed, and p is the number of variables measured in all samples. [4] [5]In this representation different rows typically represent different repetitions of an experiment, while columns represent different types of data (say, the results from particular probes).
Matrix theory is the branch of mathematics that focuses on the study of matrices. ... Descriptive statistics is concerned with describing data sets, ...
Whitening a data matrix follows the same transformation as for random variables. An empirical whitening transform is obtained by estimating the covariance (e.g. by maximum likelihood) and subsequently constructing a corresponding estimated whitening matrix (e.g. by Cholesky decomposition).
The Data Matrix symbol is a machine-readable representation of the UII. When DoD requires this marking it shall be applied directly to the surface of the item or shall be applied to an identification plate, tag or label securely fastened to the item.
Featuring Lisa Kudrow and Ray Romano, Netflix's new dark comedy "No Good Deed" is "about the highs and lows of searching for a safe, happy home."
Throughout this article, boldfaced unsubscripted and are used to refer to random vectors, and Roman subscripted and are used to refer to scalar random variables.. If the entries in the column vector = (,, …,) are random variables, each with finite variance and expected value, then the covariance matrix is the matrix whose (,) entry is the covariance [1]: 177 ...
From January 2008 to December 2012, if you bought shares in companies when John V. Faraci joined the board, and sold them when he left, you would have a 7.0 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
