spleaf.term.Matern52Kernel

class spleaf.term.Matern52Kernel(sig, rho)

Matérn 5/2 kernel.

\[k(\Delta t) = \sigma^2 \mathrm{e}^{-\sqrt{5}\frac{\Delta t}{\rho}} \left(1 + \sqrt{5}\frac{\Delta t}{\rho} + \frac{5}{3}\left(\frac{\Delta t}{\rho}\right)^2\right)\]

Parameters:

sigfloat

Amplitude (std).

rhofloat

Scale.

Methods

eval(dt[, series_id])	Evaluate the kernel at lag dt.
set_conditional_coef(*args, **kwargs)	Set the coefficients used for the conditional computations.
