I read that Spearman rho can be used to detect the presence of trend in a time
series.
However, I cannot figure out how to use such a test to thsi purpose. First of
all which one
of the available functions and how to pass my mono-channel time series which
contains both
positive and negative values.
I would love to see some examples.
Thank you very much.
