Detailed Description

Function Documentation

◆ jkqtpstatKernel2DGaussian()

double jkqtpstatKernel2DGaussian ( double  tx,
double  ty 
)
inline

a 2D Gaussian kernel function, e.g. for Kernel Density Estimation

\[ k(t_x, t_y):=\frac{1}{2\pi}\exp \left(-\frac{t_x^2+t_y^2}{2}\right) \]

◆ jkqtpstatKernel2DUniform()

double jkqtpstatKernel2DUniform ( double  tx,
double  ty 
)
inline

a 2D Uniform kernel function, e.g. for Kernel Density Estimation

\[ k(t_x, t_y):=\begin{cases}\frac{1}{4}, & \text{if }t_x,t_y\in [-1;1]\\0, & \text{else}\end{cases} \]
