Dose Response (R)


Calculates and visualizes dose response curves. This is achieved by fitting several non-linear regression models to your data.
Measurements are grouped per Compound and Concentration (see Options).
Measurements from a zero concentration are used to calculate the fit but are not displayed in the plot because of its logarithmic scale.
For a conceptual and technical overview have a look at "Bioassay Analysis using R", Ritz and Streibig, 2005, 5:12, Journal of Statistical Software.

This node is using R as back end, make sure that Rserve is running somewhere, and KNIME is accordingly configured (KNIME->Preferences). HCS-Tools Wiki
