Fast estimation of the pair correlation function
estimate_pcf_fast(pattern, ...)
pattern |
Point pattern. |

Arguments passed down to 'Kest' or 'pcf.fv'. |
The functions estimates the pair correlation functions based on an estimation of Ripley's K-function. This makes it computationally faster than estimating the pair correlation function directly.
It is a wrapper around Kest
and pcf.fv
and returns a 'Function value
object' of the spatstat
package.
