A : "He is right, along the beltline is the least stable part of Trigger's matrix."B : "Make sense, to maintain that size, the matrix **would** concentrate on the legs for support and the upper body for movement."Does this "would" mean *was going to*? or *assume something typic...
what does diagonalization mean here? ask question asked 8 years, 8 months ago modified 8 years, 7 months ago viewed 1k times 1 in a gravity theory in spacetime, the metric has signature − + + ⋅ ⋅ ⋅ + − + + · · · + . concretely this means that the metric tensor g...
What is the meaning of this symbol ⊗⊗, in particular for quaternions ? In other context it is ⊗⊗ sometimes refers specifically to the Kronecker product. In particular, we have Id⊗B=B⊕B⊕⋯⊕B d=diag(B,B,…,B d)= ⎜⎜⎜⎜⎜BB⋱B⎞⎠...
What does that mean numerically? Any matrix that you represent in floating point numbers is actually a representative of a whole bunch of matrices. Each entry is only known up to a certain precision. But this bunch of matrices does contain some matrix which is diagonalizable! This is exactly,...
where the ithith row xi∈Rpxi∈Rp of the design matrix X∈Rn×pX∈Rn×p is a vector of covariates for explaining the stochastic response yiyi (for i=1,…ni=1,…n). We know that for λ≥1n∥XTy∥∞λ≥1n‖XTy‖∞, the lasso estimate β^λ=0β^λ=0. (...

they mean, if a a is some 3x3 matrix for which there exists an x x making a x = [ 1 , 1 , 1 ] , a x = [ 1 , 1 , 1 ] , then..." it's only considered true if it's always the case. now consider the matrix you supplied, the matrix of all 1s. ...
Your model has been overfitted, because it mistakenly included a parameter which is not really relevant in the real world. It fits your sample - the 8 patients + 8 controls - very well, but it does not fit the real world data. When a model describes your sample better than it describes...
In summary: V, W,...X, and Y.In summary, the Einstein tensor for the exterior Schwarzschild solution is a 3x3 matrix containing the radial coordinate (m-2), the angular coordinate (dimensionless), and the stress-energy tensor (local conservation of energy). ...
