specparam.measures.params.compute_time_constant

specparam.measures.params.compute_time_constant(knee_freq)

Compute the characteristic time constant from the estimated knee frequency.

Parameters:

knee_freqfloat

Estimated knee frequency.

Returns:

float

Calculated time constant value, tau, given the knee frequency.

Notes

This approach for estimating the time constant comes from [1] (see [2] for code).
