"""
Compute the autocorrelation coefficients for time series data.
Here we use scipy.signal.correlate, but the results are the same as in
Yang, et al., 2012 for unbias=1:
"The autocorrelation coefficient refers to the correlation of a time
series with its own past or future values. iGAIT uses unbiased
autocorrelation coefficients of acceleration data to scale the regularity
and symmetry of gait.
The autocorrelation coefficients are divided by fc(0) in Eq. (6),
so that the autocorrelation coefficient is equal to 1 when t=0 ::
NFC(t) = fc(t) / fc(0)
Here NFC(t) is the normalised autocorrelation coefficient, and fc(t) are
autocorrelation coefficients."
Parameters
----------
data : numpy array
time series data
unbias : integer or None
unbiased autocorrelation: divide by range (1) or by weighted range (2)
normalize : integer or None
normalize: divide by 1st coefficient (1) or by maximum abs. value (2)
plot_test : Boolean
plot?
Returns
-------
coefficients : numpy array
[normalized, unbiased] autocorrelation coefficients
N : integer
number of coefficients
Examples
--------
>>> import numpy as np
>>> from mhealthx.signals import autocorrelate
>>> data = np.random.random(100)
>>> unbias = 2

"""
Compute the autocorrelation coefficients for time series data.
Here we use scipy.signal.correlate, but the results are the same as in
Yang, et al., 2012 for unbias=1:
"The autocorrelation coefficient refers to the correlation of a time
series with its own past or future values. iGAIT uses unbiased
autocorrelation coefficients of acceleration data to scale the regularity
and symmetry of gait.
The autocorrelation coefficients are divided by fc(0) in Eq. (6),
so that the autocorrelation coefficient is equal to 1 when t=0 ::
NFC(t) = fc(t) / fc(0)
Here NFC(t) is the normalised autocorrelation coefficient, and fc(t) are
autocorrelation coefficients."
Parameters
----------
data : numpy array
time series data
unbias : integer or None
unbiased autocorrelation: divide by range (1) or by weighted range (2)
normalize : integer or None
normalize: divide by 1st coefficient (1) or by maximum abs. value (2)
plot_test : Boolean
plot?
Returns
-------
coefficients : numpy array
[normalized, unbiased] autocorrelation coefficients
N : integer
number of coefficients
Examples
--------
>>> import numpy as np
>>> from mhealthx.signals import autocorrelate
>>> data = np.random.random(100)
>>> unbias = 2
>>> normalize = 2
>>> plot_test = True
>>> coefficients, N = autocorrelate(data, unbias, normalize, plot_test)
