Prevalence Estimator Data Export
Deployed
The Prevalence Estimator Data Export is the second of three models used after sampling has occurred and no positive cases are found to estimate the latent prevalence of CWD.
The Prevalence Estimator Data Export allows users to pre-process CWD Data Warehouse sample data for upload and use in the SpeedGoat Estimation Tool. Of particular interest is the upper bound of the credible interval, which means there is, for example, a 95% probability that true prevalence is at or below the reported level given your sampling effort.
Unlike the Simple Undetected Prevalence Estimator, which does not use any auxiliary information for prevalence estimation, or the Probability Disease Freedom Using Clustering Model which considers host clustering in prevalence estimation, the SpeedGoat Estimation Tool uses prior distributions to estimate prevalence. Only certain prior distributions are accommodated, so sample data depicting select species or sources may not be considered.
