Hi,

the results provided by the mandel.fqcs() function for the h statistic are
at odd with other similar fuctions, such as the metRology package.

It appears that the estimation of the h statistic in function h.qcs.lab.qcdata()
is using the S statistic

h.i[,i] <- (mean.i[ind]-statistics$mean[i])/statistics$S[i]

where it should be SB to conform to the definition of Mandel h.
