Abstract: A method includes receiving measured activity from a first assay, the first assay comprising wells containing compounds and first controls. The measured activity may be indicative of activation or inhibition by the compounds on a process. The method includes determining an estimate of activity percentages of the compounds. The estimate of the activity percentages of the compounds may be based on a noise distribution, and the noise distribution may be based on the first controls. The method includes receiving a first reference based on a required activity percentage of compounds for the first assay. The method includes receiving a second reference based on a required accuracy percentage of the compounds identified as active according to the first reference. The method includes identifying active compounds of the first assay based on the first reference, the second reference, the measured activity, and the estimate of activity percentages.
