Table 3 Particular settings of Campbell and Steele’s [5] method

10C

10 chains

When comparing our methods, it was of interest to see how the performance depended on the number of parallel MCMC chains, as originally the authors used 4 chains

Obs20

20 observations

Originally, the authors use 401 observations. We reduced this to a dataset size more usual with these types of experiments to observe the dependency of the methods on the amount of data

15K

15 knots

The method in C&S uses B-splines interpolation. We changed the original tuning parameters from the authors' paper to observe the sensitivity of the parameter estimation by these tuning parameters

P3

polynomial order 3 (cubic spline)

The original polynomial order is 5 and again, we wanted to observe the sensitivity of the parameter estimation by these tuning parameters
