expcomp: Comparison of several sigmodal models by RMSE within the exponential region
Description
The exponential region of the qPCR data is identified by the studentized outlier method, as in expfit.
The root-mean-squared-errors of 14 different sigmoidal models within this region are then calculated.
The result of the fits are plotted and the models are returned in order of ascending RMSE.
Usage
expcomp(object, ...)
Arguments
object
a 'drc' object.
...
other parameters to be passed to expfit.
Value
A dataframe with names of the models and the respective RMSEs.
Details
The following sigmoidal models are fitted:
b3(), b4(), b5(), l3(), l4(), l5(), LL2.3(), LL2.4(), LL2.5(), baro5(), w3(), w4(), W2.3(), W2.4()
