The Biological Assay Simulation Package provides document types for the simulation of Quantitative response assays (QRA) from the Biological Assay Package version 26. The QRA Collector document type allows for aggregating already calculated QRA documents to prepare parameter estimates of the regression models for simulation. The QRA Simulator document type simulates any number of QRA documents based on a source document, such as the QRA Collector. Choose whether to apply response transformation and fine-tune the scattering of simulation data. The QRA Simulator works for all regression models (parallel-line, 3-, 4-, 5-parameter logistic curves, slope ratio) implemented in the QRA document.
