That went down in June. I've moved to Bluehost and WordPress. Wish me better luck.

Bayesian methods for WiSAR. The MapScore project described here provides a way to evaluate probability maps using actual historical searches. On a metric where random maps score 0 and perfect maps score 1, the ISRID Distance Ring model scored 0.78 (95%CI: 0.74-0.82, on 376 cases). The Combined model was slightly better at .81 (95%CI: 0.77-0.84). Our MapScore paper is now in press at. Continue reading "Forthcoming MapScore Paper! February 22, 2015. February 22, 2015.
