ecf {empichar} | R Documentation |
Empirical characteristic function of a d-dimensional random variable. This function is evaluated at m vectors of size d.
ecf(t, smp)
t |
mxd matrix where the function will be evaluated. |
smp |
nxd matrix with sample size if size n. |
This function must receive matrices or vectors. It is a wrapper function that allows more general inputs.
A complex vector of size m with the empirical characteristic function.
