TypeError when using JidtDiscreteCMI

[Rhydderch]

Hello,

When I try to use the estimator for discrete data, I get the following error:

TypeError: No matching overloads found for constructor infodynamics.measures.discrete.ConditionalMutualInformationCalculatorDiscrete(), options are:
    public infodynamics.measures.discrete.ConditionalMutualInformationCalculatorDiscrete(int,int,int)

Here's my code:

#data structure: 6 processes, 56 samples/time points, 39 replications (3D array: 39x56x6)
dat = Data(mydata, dim_order='rsp')
network_analysis = MultivariateTE()
settings = {
  'cmi_estimator': 'JidtDiscreteCMI',
            'max_lag_sources': 3,
            'min_lag_sources': 0
          }

results = network_analysis.analyse_network(settings=settings, data=dat)

What am I doing wrong here?

PS: I don't encounter the same errors with the "OpenCLKraskovCMI" for continuous data (though, my variables range from 0-100, so I'm not sure the KSG estimator is the right choice)

Hi,

if your variables range from 0-100 and almost all values are there, you should perhaps use the kraskov estimator (with some added epsilon noise), because the discrete estimator will not be able to work with so many symbols in the alphabets of your variables.

Hi Michael,

Thank you very much for your answer and for clarifying. The kraskov estimator works well.
