esem.abc_sampler.ABCSampler.batch_constrain

ABCSampler.batch_constrain(sample_points, tolerance=0.0, threshold=3.0, batch_size=1)

Constrain the supplied sample points based on the tolerance threshold, optionally in bathes.

Return a boolean array indicating if each sample meets the implausibility criteria:

I < T

Return True (for a sample) if the number of implausibility measures greater than the threshold is less than or equal to the tolerance

Parameters

• sample_points (ndarray) – An array of sample points which are to be emulated and compared with the observations

• tolerance (float) – The fraction of samples which are allowed to be over the threshold

• threshold (float) – The number of standard deviations a sample is allowed to be away from the obs

• batch_size (int) – The size of the batches in which to perform the constraining (useful for large samples)

Returns

ndarray – A boolean array which is true where the (emulated) samples are compatible with the observations and false otherwise
