Data 605 Discussion Week 3
Load library suppressWarnings( library(tinytex) ) Question T10 Page 307 A matrix \(A\) is idempotent if \(A^2 = A\). Show that the only possible eigenvalues of an idempotent matrix are \(\lambda = 0\) and \(\lambda = 1\).Then give and example of a matrix that is idempotent and has both of these two values as eigenvalues. Let \(\lambda\) b...

suppressMessages( library(tidyverse) ) Problem Set 1.1 Show that ATA \(\neq\) AAT in general form Let A be a m by n matrix such that _m \(\neq\) n. Therefore _ATA will equal a matrix with dimension n by n. While AAT will equal a matrix with dimension m by m. Since m \(\neq\) n, then ATA \(\neq\) AAT. QED For example: A <- matrix(seq(1,...

For this assignment I decided to use the map() function in the **purrr* package of the tidyverse. I chose map() because it allows for element operation of a vector or list. It gives us a replacement for for loops. library(tidyverse) ## ── Attaching core tidyverse packages ───────────────────────�...
