If a matrix is idempotent, then its eigenvalues are either 0 or 1 (since its minimal polynomial is \lambda^2-\lambda ). nilpotent 幂零的 :A^k=0 In words: If a matrix raised to a whole number equals zero matrix, then we say this matrix is nilpotent. If a matrix is nilpotent, th...
We're an all-remote company that allows people to work from almost anywhere in the world. It's important for us to practice clear communication in ways that help us stay connected and work more efficiently.

The matrix X’i,t includes all regressors at a regional level. The correlation of the lagged dependent variable, yi,t−1, with the fixed effects in the error term, causes Nickell (1981) dynamic panel bias, which can be overcome by taking the first differences of the original model (...
According to the cubical modular method, therefore, every house member can be designed within a cube matrix. The cube, as a basis of design, provides more than a mere geometric six-sided figure. Within it may be specifically located all the special and particular requirements of structure...
2, so it need not be explicitly stored as a matrix. The iterative solution technique we use starts with an initial "guess" for the solution,x(0), and each stepkproduces an improved solution,x(k). The superscript notation indicates the iteration number. The simplest iterative techniq...
从金融学估值模型和 common sense 出发,可以猜测公司质量高应该能导致其未来基本面的持续优异,而公司股票的高收益率则是基本面优异的结果。而最能反应基本面持续优异的变量大概要数未来盈利增长(future earnings growth)。从另一个角度来说,未来盈利增长可以被视为简化版的 SUE(用去年同期的 earnings 作为 naïve ...
Datasets coming from different samples were integrated using integrative non-negative matrix factorization as implemented in LIGER v.0.5.0 (ref. 105). The datasets were integrated at two levels: (1) integration of replicates coming from the same brain region (that is, telencephalon, diencephalon, ...
These 22 data types range from the basics like byte, int, and double to more exotic types like Matrix, Point3D, and Quaternion. The animation facilities in Windows Presentation Foundation are surely an impressive piece of work, but only a non-programmer would consider those 22 data types to ...
In (5), ‘routinely’ exclusively modifies ‘evaporate’. The matrix predicate ‘evaporate’ is closer in terms ofstructural distanceto ‘routinely’ than to ‘rhyme’, since the relative clause embeds ‘rhyme’ more deeply (minimal search is partly “defined by least embedding”; Chomsky,2004,...
