Generalized Inverse and Projectors - Michigan State University

A.12 Generalized Inverse 511 Theorem A.70 Let A: n × n be symmetric, a ∈R(A), b ∈R(A),and assume 1+b A+a =0.Then (A+ab)+ = A+ −A +ab A 1+b A+a Proof: Straightforward, using Theorems A.68 and A.69. Theorem A.71 Let A: n×n be symmetric, a be an n-vector, and α>0 be any scalar. Then the following statements are equivalent: (i) αA−aa ≥ 0. (ii) A ≥ 0, a …

Step by Step Tutorial to creating R Packages

Build an R Package -- Step 6. Build and install the R package •In search box, type command prompt •In command prompt, change directory to the place that contains the R package •Build R package using R CMD build pkgName. For example I use R CMD build cum. A tar.gz file is built under the working directory.

Chapter 4 Multivariate distributions

RS – 4 – Multivariate Distributions 3 Example: The Multinomial distribution Suppose that we observe an experiment that has k possible outcomes {O1, O2, …, Ok} independently n times.Let p1, p2, …, pk denote probabilities of O1, O2, …, Ok respectively. Let Xi denote the number of times that outcome Oi occurs in the n repetitions of the experiment.
