g.X(12), where X is a square matrix. Does anyone know how to compute the inverse square root of Square root matrix stata manual matrix in Stata? I cannot seem to find any info on this either the programming manual or the matrix information in the User's Compute the Square Root of the Elements of a Diagonal Matrix. Stata& Mata Sidebyside Stata Mata mat D: D mat Here is how we can compute the group total and mean vector and the mean matrix.
Using Stata How do I do elementwise operations on a matrix? Stata FAQ Here is a small (33) Stata example of a matrix in which each element is exponentiated. You can generalize this example to any kind of elementwise matrix operation.
Cholesky squareroot decomposition: cholinv() Symmetric, positivedefinite matrix inversion: Make square matrix symmetric (Hermitian) matexpsym() Exponentiation and logarithms of symmetric matrices publishes books, manuals, and journals about Stata and general statistics topics for professional researchers of all disciplines.
Dec 01, 2013 I am new to Stata and I am doing Relative Importance Analysis case, where I have to deal a lot with matrices and I don't know how to do a square root of a matrix (find matrix X such that X2A). I tried looking through all the formulas including those for decomposition and I am stuck.
