class BSplineRatio(n_splines, q, q_inj, qmin=0, basis=<class 'gwinferno.interpolation.LogYBSpline'>, **kwargs)[source]#

Bases: Base1DBSplineModel

A B-Spline model for the binary mass ratio.

Parameters:
n_splinesint

Number of basis functions, i.e., the number of degrees of freedom of the spline model.

qarray_like

Mass ratio parameter estimation samples for basis evaluation.

q_injarray_like

Mass ratio injection samples for basis evaluation.

qminfloat, default=0

Minimum mass ratio. Ignored if xrange is provided.

basisclass, default=LogYBSpline

Type of basis to use.

Methods

eval_spline(bases, coefs)

Given design matrix bases and coefficients coefs, project coefficients onto the basis.

inj_pdf(coefs)

Project the coefficients coefs onto the design matrix evaluated at the injection samples.

pe_pdf(coefs)

Project the coefficients coefs onto the design matrix evaluated at the parameter estimation samples.

__call__(coefs, pe_samples=True)#

Evaluate the projection of the coefficients along the design matrix over the parameter estimation or injection samples. Use flag pe_samples to specify which samples are being evaluated (parameter estimation or injection).

Parameters:
coefsarray_like

Basis spline coefficients.

pe_samplesbool, default=True

If True, design matrix is evaluated across parameter estimation samples. If False, design matrix is evaluated across injection samples.

Returns:
array_like

The linear combination of the basis components evaluated at the parameter estimation or injection samples given the coefficients.
