Three experimental datasets from two water sediment systems and one soil

The datasets were used for the comparative validation of several kinetic evaluation software packages (Ranke, 2014).

test_data_from_UBA_2014

Format

A list containing three datasets as an R6 class defined by mkinds. Each dataset has, among others, the following components

title

The name of the dataset, e.g. UBA_2014_WS_river

data

A data frame with the data in the form expected by mkinfit

Examples

  # This is a level P-II evaluation of the dataset according to the FOCUS kinetics
  # guidance. Due to the strong correlation of the parameter estimates, the
  # covariance matrix is not returned. Note that level P-II evaluations are
  # generally considered deprecated due to the frequent occurrence of such
  # large parameter correlations, among other reasons (e.g. the adequacy of the
  # model).
