Hi guys, I am trying to write a function that allows me to perform specific transformations to each element of a 2 by 2 matrix to generate a 3 by 3 matrix. Input into function-2 by 2 matrix Output from function -3 by 3 matrix For example: # a is my original 2 by 2 matrix #b is my new 3 by 3 matrix set.seed(2) a=matrix(rnorm(4),ncol=2) #let's say these are the transformations i wish to

Hi all, I have a 4 by 100 matrix. I wish to extract each column and make it into a 2 by 2 matrix. I also want to assign names for each 2X2 matrix. For example set.seed(2) a=matrix(rnorm(400),ncol=100) a1=matrix(a[,1],ncol=2) a2=matrix(a[,2],ncol=2) . . . a100=matrix(a[,100],ncol=2) Any simple ideas. Thanks. B -- View this message in context:

hi guys, I am using trivariate VAR model to get 10 step ahead orthogonalized impulse response functions. I want to use rolling sample analysis on the coefficients of the irf but I have no idea how to do that. I looked through the forums but I can't seem to find any solutions. Any suggestions would be helpful. B -- View this message in context:
