+Calculate the minimum error to assume in order to pass the variance test +

+ +
+
+

Usage

+ 
mkinerrmin(fit, alpha = 0.05)
+ +

Arguments

+
+
fit
+
+ an object of class mkinfit. +
+
alpha
+
+ The confidence level chosen for the chi-squared test. +
+
+ +
+

Description

+ +

This function uses optimize in order to iteratively find the +smallest relative error still resulting in passing the chi-squared test +as defined in the FOCUS kinetics report from 2006.

+ +
+ +
+

Value

+ +

+ A dataframe with the following components: +
err.min
The relative error, expressed as a fraction.

+ +

n.optim
The number of optimised parameters attributed to the data series.

+ +

df
The number of remaining degrees of freedom for the chi2 error level + calculations. Note that mean values are used for the chi2 statistic and + therefore every time point with observed values in the series only counts + one time.

+ +

The dataframe has one row for the total dataset and one further row for + each observed state variable in the model. +

+ +
+ +
+

Details

+ +

This function is used internally by summary.mkinfit.
