QuantileInterpolator

class pyirf.interpolation.QuantileInterpolator(grid_points, bin_edges, bin_contents, quantile_resolution=0.001)

Bases: DiscretePDFInterpolator

Methods Summary

interpolate(target_point)

Takes a grid of binned pdfs for a bunch of different parameters and interpolates it to given value of those parameters.

Methods Documentation

interpolate(target_point)

Takes a grid of binned pdfs for a bunch of different parameters and interpolates it to given value of those parameters. This function provides an adapted version of the quantile interpolation introduced in [1]. Instead of following this method closely, it implements different approaches to the steps shown in Fig. 5 of [1].

Parameters:

target_point: numpy.ndarray, shape=(O)

Value for which the interpolation is performed (target point)

Returns:

f_new: numpy.ndarray, shape=(1,…,M,…)

Interpolated and binned pdf
