Hello All,

I have been trying to perform the “Nonlinear Granger causality test in R” however I didn't understand specific parameters ( LayersUniv, LayersBiv) from the below formula.

What values do I need to insert in “ LayersUniv, LayersBiv”. What is the purpose of these parameters?

How to perform this test?

nlin_causality.test( ts1,

ts2,

lag,

LayersUniv,

LayersBiv,

iters = 100,

learningRate = 0.1,

algo = "sgd",

bias = TRUE, activationsUniv = vector(), activationsBiv = vector()

)

I have googled it but I didnt find exact solution to my problem. Kindly help me out.
