Fri, 05 Oct 2018 17:46:02 +0000http://andrewpwheeler.wordpress.com/?p=1468#comment-5165[…] for crime analysts, as they have a high probability of being linked to the same offender(s). Building off of some prior work, I wrote some python code to see what the distribution of these strings would look like when you […]

p.s. the variance formula seems wrong ðŸ˜‰

Fri, 28 Sep 2018 13:13:04 +0000http://andrewpwheeler.wordpress.com/?p=828#comment-5136You can’t do that in the crimCV package unfortunately. You can do it in the Proc Traj package for Stata though FYI.

Thu, 27 Sep 2018 23:56:19 +0000http://andrewpwheeler.wordpress.com/?p=828#comment-5134Sorry if I was unclear. Let’s say you are testing a model with 3 groups, in SAS Proc Traj, you can indicate the order of polynomial trends to test for each of the groups. For instance, you can specify a quadratic for group 1, linear for group 2, and so on. It seems with crimCV, you can only choose one trend that is applied to each of the groups.

In SAS Proc Traj, you can assign separate ordered polynomials for each of the groups — my attempts to do so in crimCV have failed. Do you know if this is possible? Thanks!

Tue, 25 Sep 2018 16:25:29 +0000http://andrewpwheeler.wordpress.com/?p=1758#comment-5124[…] the ECCA conference this past spring Jerry Ratcliffe asked if I could apply some of my prior work on evaluating changes in crime patterns over time to make a set of confidence intervals for the weighted displacement quotient statistic (WDQ).
