qmvnorm function
Dear all,
I need to use the "qmvnorm" function in mtvnorm package.
Here is the error message I got
> qmvnorm(0.05, tail="upper", sigma=var)$quantile
Error in uniroot(pfct, interval = interval) :
f() values at end points not of opposite sign
There is no problem for 50th quantile.
> qmvnorm(0.5, tail="upper", sigma=var)$quantile
[1] -0.5325527
Can anyone give some hint regarding this?
Thanks.
