in order to return more multiple variables, you can put them in a list
and then return this list.
e.g.
#Function A
boot-function(a,b,c){
mean_boot-(a+b)/2
var_boot-c
list(mean_boot = mean_boot, var_boot = var_boot)
}
out - boot(1,2,3)

Say I have a csv file, each row contains several fields, one of them

In history data, I have all the fields including the result of whether
it is success. In future data, I only have fields without the result.
For example:

Since you have an under-determined system of linear equations, you have
infinitely many solutions. One reasonable solution is the minimum-norm
solution. You can obtain this from singular-value decomposition as follows:
# Minimum norm solution `x': A %*% x = b, such that ||x|| is minumum

What I'm really interest in are the functions that can do GEV, probit, and
mixed logit. I searched R, and I did find the function that can do the
regular multinomial logit model, but I did not see the function that can
do GEV, probit, and mixed logit. Any further advices?

Hi all,
The problem is solved uninstalling the R and restarting the system and
installing it again. I don't know what caused the error but reinstalling the
R was not enough and the system must be restarted.

I cannot reproduce what you mentioned. One possible is that you use
