Estimation of sigma_yx
get_sigma_yx(Y, X, x, h, inf_k)
Y |
A numerical vector representing the sample data of variable Y. |
X |
A numerical vector representing the sample data of variable X. |
x |
The specific point at which sigma_yx is to be estimated. |
h |
A bandwidth parameter used in the kernel function for smoothing. |
inf_k |
A kernel function used to weigh observations in the neighborhood of point x. |
Returns a scalar representing the estimated value of sigma_yx at the point x.
