Compute log sample average of fourier transform and get mod
Usage
get_avg_phi_log(Y = 1, X, ln_xi)
Arguments
- Y
A numerical vector representing the sample data of variable Y.
- X
A numerical vector representing the sample data of variable X.
- ln_xi
A single numerical value representing the log frequency at which the Fourier transform
is computed.
Value
Returns the log sample estimation of expected Fourier transform at frequency xi.
