class BSplineMass(n_splines, m, m_inj, mmin=2, mmax=100, basis=<class 'gwinferno.interpolation.LogXLogYBSpline'>, **kwargs)[source]#

Bases: Base1DBSplineModel

A B-Spline model for the mass of a single binary component.

Parameters:

n_splinesint: Number of basis functions, i.e., the number of degrees of freedom of the spline model.
marray_like: Component mass parameter estimation samples for basis evaluation.
m_injarray_like: Component mass injection samples for basis evaluation.
mminfloat, default=2: Minimum component mass. Ignored if xrange is provided.
mmaxfloat, default=100: Maximum component mass. Ignored if xrange is provided.
basisclass, default=LogXLogYBSpline: 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.
