My guess is that there are two ways that you might explore to do this.

  1. Any time someone says 'statistics', my first thought is 'R'; I
  don't know any of the things you're talking about here, but if these
  are statistical methods of some sort, R seems like a valid place to
  start looking. 


    rgdal will let you read OGR data sources (like PostGIS databases)
    into a spatial vector object, and interact with them from there.
  2. I know that at least some of these mechanisms (like Kriging) are 
     implemented in GRASS, and I would bet that this is your second best
     option. GRASS is a bit intimidating to a first time user (though I
     guess not much more so than R :)), but a very powerful geographic
     data analysis tool.

Best of luck,
