Fits dose-response models using an evolutionary
algorithm to estimate the model parameters. The procedure currently
can fit 3-parameter, 4-parameter, and 5-parameter log-logistic models
as well as exponential models. Functions are also provided to plot,
make predictions, and calculate confidence intervals for the resulting
models. For details see "Nonlinear Dose-response Modeling of
High-Throughput Screening Data Using an Evolutionary Algorithm",
