qmctorch.utils.stat_utils module

qmctorch.utils.stat_utils.blocking(x, block_size, expand=False)

block the data

Parameters:

• x (data) – size Nsample, Nexp
• block_size (int) – size of the block

qmctorch.utils.stat_utils.correlation_coefficient(x, norm=True)

Computes the correlation coefficient

Parameters:

• x (np.ndarray) – measurement of size [Nsample, Nexperiments]
• norm (bool, optional) – [description]. Defaults to True.

qmctorch.utils.stat_utils.integrated_autocorrelation_time(correlation_coeff, size_max)

Computes the integrated autocorrelation time

Parameters:

• correlation_coeff (np.ndarray) – coeff size Nsample,Nexp
• size_max (int) – max size

qmctorch.utils.stat_utils.fit_correlation_coefficient(coeff)

Fit the correlation coefficient

to get the correlation time.

Parameters:coeff (np.ndarray) – correlation coefficient Returns:correlation time, fitted curve Return type:float, np.ndarray
