Experimental: compute the standard deviation of the score as well as the mean in the update and use it to improve the information matrix estimate |

We don't support weights |
subset |
If you want to analyze a subset, use |
For a dataset of size N
the subsample is of size N^(5/9)
. Unless N
is large the approximation won't be very good. Also, with small N
it's quite likely that, eg, some factor levels will be missing in the subsample.
