median.fdt
calculates the value of the median based on a known formula.
median.fdt.multiple
calls mean.fdt
for each variable, that is, each column of the data.frame.
mean.fdt
returns a numeric vector containing the value of the median of the fdt
.
median.fdt.multiple
returns a list, where each element is a numeric vector
containing the value of the median of the fdt
for each variable.
