rna_majiq.DeltaPsiPMF

class rna_majiq.DeltaPsiPMF(p)

Specialization of PMFSummaries for DeltaPsi on [-1, 1]

Parameters:

p (xarray.DataArray) – Probability distribution(s) over intervals (dimension: pmf_bin) Dimensions: […, “pmf_bin”] Coordinates: pmf_bin_start, pmf_bin_end (…, “pmf_bin”) First pmf_bin_start must be -1, Last pmf_bin_end must be 1

__init__(p)

Initialize DeltaPsiPMF with given probability vector

Parameters:

p (xarray.DataArray) – Probability distribution(s) over intervals (dimension: pmf_bin) Dimensions: […, “pmf_bin”] Coordinates: pmf_bin_start, pmf_bin_end (…, “pmf_bin”) First pmf_bin_start must be -1, Last pmf_bin_end must be 1

Methods

__init__(p)	Initialize DeltaPsiPMF with given probability vector
f_expectation(p, f)	expectation of array f over distribution p
interval_probability(a, b)	compute probability of value on interval [a, b]
interval_width(a, b)	width of interval [a, b]
probability_changing([changing_threshold])	Probability that abs(dPSI) > changing_threshold
probability_nonchanging([nonchanging_threshold])	Probability that abs(dPSI) <= nonchanging_threshold

Attributes

bin_end	end of each bin
bin_start	start of each bin
bin_width	extract width of each bin for PMF
mean	expectation of position in bins
midpoints	midpoints of PMF bins
standard_deviation	standard deviation (sqrt of variance)
variance	variance of position (between bins, and within bins)
variance_across_bins	variance choosing between bins (treating as point mass at midpoints)
variance_per_bin	variance of position in a selected bin under uniform distribution
