Hi All,
I need to fit a mutlivariate normal model to a dataset in order to
obtain the mean and covariance parameters. I see that the MVN
function in the MCLUST package can do this, however when I try to
run even the simplest example provided in the documentation, as
below, I get the following error:
n <- 1000
set.seed(0)
x <- rnorm(n, mean = -1, sd = 2)
mvn(modelName = "X", x)
Error in .Fortran("mvn1d", as.double(data), as.integer(n), double(1), :
Fortran symbol name "mvn1d" not in DLL for package "mclust"
I cannot see a resolution to this in the list, and wonder whether I
need to load something else separately to the package? Could it be
that I need to load a separate DLL?
Please the footer of this message. It works for me, and we need the
'at a minimum' information we asked for to begin to guess what might
be wrong for you.
However, this is pretty much overkill: there is nothing 'mutlivariate'
about your example, and even if there were mean() and var() give the
standard parameter estimates.
Many thanks for your help.
