New subject: Memory problems using Zelig-multiply imputed data set s

23 Jul 2004

Hi,

 I have similar memory problems.  I am using 5 multiply imputed data sets.
I have tried both fixes suggested in the How-to link you provided.  I do not
have access to a Unix system.  What else can people with large or multiple
data sets do on a Windows system?

Thanks,

Sean Richey

Hi David,
  Have you tried everything on the following page? 
http://gking.harvard.edu/zelig/docs/How_do_I2.html
  If you have an access to Unix server, then it would be best if you could 
run your model on that server rather than Windows.

  Hi all,

 I'm trying to find some help with some memory problems.
 I've been reading the FAQ archive on this topic and I could see that I'm
not 
...
  the first one with this issue. The solutions included
in previous posts did 
...
  not work with my model and dataset.

 I am trying to estimate a bivariate probit model. The fact is that my model 
...
  includes 27 variables (considering the explanatory
ones included in the two 
...
  equations) and about 60.000 records (but I also tryied
with a sub-sample of 
...
  about 20.000).

 The mesagge i obtain is the following:

 Error: cannot allocate vector of size 287850 Kb
 In addition: Warning message:
 Reached total allocation of 904Mb: see help(memory.size)

 My PC has 512 MB RAM and is running with a P-IV and and W2K(Proffesional)

 Does anyone know what could be the upper limit that i would be able to 
 manage in terms of dataset size?

 And, more important, with my model and dataset, and having tryied the 
 suggested alternatives in the FAQ, does anyone have another suggestion on 
 this?

 Many thanks in advance.

 David Mermelstein
