If you are exploring PK/PD modeling, the Certara Phoenix platform offers specialized, validated tools to ensure your data meets regulatory standards.
Below is an overview of its purpose, core features, and how it is used in professional and academic settings. What is Nonlin? Nonlin is a computer application designed to perform nonlinear dynamic time-history analysis nonlin software
"You have 5 data points and you want to fit a model with 10 parameters? The software will cry." Nonlinear models require vast amounts of data relative to linear models. Without enough data, the software returns "singular gradient matrix" errors. If you are exploring PK/PD modeling, the Certara
