Fitting mean and covariance of Multivariate normal with censored data
Hello,
I have been googling for 2 days and I cannot find the answer in
previous posts.
I have a set of d-dimensional data elements (d=11 .. 14), each data
point can be censored at different values both
Lower-limit and upper limit.
N = 2000 sets of vectors of
D=11 data points per vector.
Each of the N*D points can have different upper and lower limits.
I "simply" want to fit a

"no visible global function definition" using R-Devel check utility
...ng note:
.
assetsMeanCov: no visible binding for global variable 'scaleTau2'
.
I'll try to explain why with a minimal example. Let's have a look at the
following function:
assetsMeanCov <- function(x, method = c("cov", "MCD", "OGK"), alpha = 1/2,
sigmamu = scaleTau2, ...) {
if (method == "cov") {cov(x, ...)}
if (method == " MCD") {robustbase::covMcd(x, alpha = alpha, ...)}
if (method == " OGK") {robustbase::covOGK(x, sigmamu =
substitute(sigmamu), ...)}
}
where robustbase is mentioned under "Suggests:&qu...
