+
+ +

The 12 datasets were generated using four different models and three different + variance components. The four models are either the SFO or the DFOP model with either + two sequential or two parallel metabolites.

+ +

Variance component 'a' is based on a normal distribution with standard deviation of 3, + Variance component 'b' is also based on a normal distribution, but with a standard deviation of 7. + Variance component 'c' is based on the error model from Rocke and Lorenzato (1995), with the + minimum standard deviation (for small y values) of 0.5, and a proportionality constant of 0.07 + for the increase of the standard deviation with y.

+ +

Initial concentrations for metabolites and all values where adding the variance component resulted + in a value below the assumed limit of detection of 0.1 were set to NA.

+ +

As an example, the first dataset has the title SFO_lin_a and is based on the SFO model + with two sequential metabolites (linear pathway), with added variance component 'a'.

+ +

Compare also the code in the example section to see the degradation models.

Format

+ +

A list containing datasets in the form internally used by the 'gmkin' package. + The list has twelfe components. Each of the components is one dataset that has, + among others, the following components +

+
title
The name of the dataset, e.g. SFO_lin_a
+
data
A data frame with the data in the form expected by mkinfit
