Abstract

Statistical comparison of AGDISP prediction were made against data obtained during aerial spray field trials ("Mission III") conducted in March 1987 at the APHIS Facility, Moore Air Base, Edinburg, Texas, by the NEFAAT group (Northeast Forest Aerial Application Technology). Seven out of twenty one runs were observed and predicted means (O and P), mean bias error (d) standard deviation of the difference (od), root mean square error of the difference (RMSE), and average absolute gross error of the difference (|d|), index of agreement (r), variance comparison (Var), fraction of positive residuals (f_p) and average relative error (RE=RMSE/O) of prediction.
