Simulated data with a 10x5 factorial design with two replications. The true PRC curves are diverging straight lines as given in FigS2 of ter Braak (2023) with an interaction effect that is half the main effect of the second factor. The data and design as analysed in ter Braak (2023) has one empty cell (cell A10, B5).
The data has 100 unit and 10 colums as follows:
case identifier for a sample e.g. A2B3.1 the replicate of cell
for the levels 2 and 3 of the factors A and B, respectively.
A factor A, taken as Time variable in the classical PRC of ter Braak (2023)
B factor B, taken as Treatment variable in the classical PRC of ter Braak (2023)
V1 value of response variable 1 and so on for the remaining 6
response variables
