I have a question regarding the Morris method in the differential equation package. The documentation does not describe how the number of trajectories is calculated for the Morris method. In the example given for the LotkaVolterra model with 4 parameters, an unusually large number of trajectories is included in the input
m = gsa(f1,Morris(total _num_trajectory=1000,num_trajectory=150),[[1,5],[1,5],[1,5],[1,5]])
From what I have read about the method, for 4 parameters the number of trajectories would be 5x(r=8) or 40 trajectories at most. Do you know how the numbers 1000 and 150 are calculated for the Lotka Volterra model and what they represent?
Implement a
sensitivity(::ODEProblem,tspan)
which applies Morris global sensitivity analysis on a ParameterizedFunction.http://www.abe.ufl.edu/Faculty/jjones/ABE_5646/2010/Morris.1991%20SA%20paper.pdf http://www.math.ualberta.ca/~hwang/sensitivity http://discovery.ucl.ac.uk/19896/1/19896.pdf
