Dear Satalist,

I am running a quantile regression with 25 independent variables and
bootstrapped standard errors.  When I use 250 reps, I get the
following error message:

Bootstrap replications (250)
----+--- 1 ---+--- 2 ---+--- 3 ---+--- 4 ---+--- 5
..............................
....................    50
..................................................   100
..................................................   150
..................................................   200
..................................unable to restore data due to
insufficient memory; try discard first
unable to restore data due to insufficient memory; try discard first
unable to restore data due to insufficient memory; try discard first


Below is my memory allocation. I am using a cluster, so the program is
able to run on multiple processors.


Current memory allocation

                    current                                 memory usage
    settable          value     description                 (1M = 1024k)
    --------------------------------------------------------------------
    set maxvar        11000     max. variables allowed           3.935M
    set memory        15360M    max. data space             15,360.000M
    set matsize       11000     max. RHS vars in models        924.080M
                                                            -----------
                                                            16,288.015M


Is there anything I can do to fix this?


Thanks,
Jackie
