Hi Dear All,
This is a function which contains Covariance Ratio and Likelihood
Distance
values (CVRi, LDi). i want to compute the all row's values, that is
run this
function for nrow(X) times. The X and Y matrices are;
X<-
matrix(c(1125,920,835,1000,1150,990,840,650,640,583,570,570,510,555,460,275,510,165,244,79,232,268,271,237,192,202,184,200,180,165,151,171,243,147,286,198,196,210,327,334,7160,8804,8108,6370,6441,5154,5896,5336,5041,5012,4825,4391,4320,3709,3969,3558,4361,3301,2964,2777,85.9,86.5,85.2,83.8,82.1,79.2,81.2,80.6,78.4,79.3,78.7,78.0,72.3,74.9,74.4,72.5,57.7,71.8,72.5,71.9,8905,7388,5348,8056,6960,5690,6932,5400,3177,4461,3901,5002,4665,4642,4840,4479,4200,3410,3360,2599),nrow=20)

theta <- function(X,Y) {

Y.cap <- P%*%Y
e <- Y-Y.cap
var.cap<-(t(e)%*%e)/(nrow(X)-ncol(X)-1)
ei <- Y[i,]-X[i,]%*%B.cap
pi <- P[i,i]
var.cap.i <-
(((nrow(X)-ncol(X)-1)*var.cap)/(nrow(X)-ncol(X)-2))-(ei^2/((nrow(X)-
ncol(X)-2)*(1-pi)))
ti <- ei/(sqrt(var.cap)*sqrt(1-pi))
ti.star <- ei/(sqrt(var.cap.i)*sqrt(1-pi))
X.star <- cbind(X,Y)
pi.star <- pi+(ei^2/(t(e)%*%e))
LDi <- nrow(X)*log(((nrow(X))/(nrow(X)-1))*(((nrow(X)-ncol(X)-2))/
(ti.star^2+nrow(X)-ncol(X)-2)))+((ti.star^2*(nrow(X)-1))/((1-
pi)*(nrow(X)-ncol(X)-2)))-1
CVRi <- (((nrow(X)-ncol(X)-1-ti^2)/(nrow(X)-ncol(X)-2))^(nrow(X)))/
(1-pi)
list(ti=ti,ti.star=ti.star,pi=pi,pi.star=pi.star,LDi=LDi,CVRi=CVRi) }
obj<-list()
for(i in 1:nrow(X)){
X<-X
Y<-Y
out<-theta(X,Y)
obj<-c(obj,list(out))}
obj
Finally i get values...
Is there any way to get the outputs as a list or data.frame like
Try this:
do.call(rbind, obj)

Thanks so much for any idea !
