Randomly impose a monotone missingness pattern by replacing the ends
of each column of the input matrix by a random number of NA

a two-vector of alpha ( |
The returned x
always has one (randomly selected)
complete column, and no column has fewer than m
non-missing entries. Otherwise, the proportion of missing entries
in each column can be uniform, or it can have a beta
distribution with parameters alpha (ab[1]
) and
beta (ab[2]
)
returns a matrix
with the same dimensions as the input x
