Yes it's possible. I did this a few years ago as a learning project, and the relevant lua scripts can be seen here: https://gist.github.com/dbro/9920666.

... but I wouldn't claim that it's done efficiently. From the comments in the code's tests:

    # some results based on running speed tests on a lightweight netbook:
    # standard error = 0.01, 10kb of registers
    # < 1 ms per init()
    # < 1 ms per update()
    # < 1 ms per count() for single set
    # ~30 ms per set for count() of union of sets
