• Resumen

  • A new second order statistic based on the mark correlation function to analyse spatial point patterns with functional marks is presented. An edge corrected estimator is defined and illustrated through a simulation study and two data sets involving two spatially explicit demographic functions, namely, the town population pyramid and the demographic evolution from 1996 to 2008 involving 121 towns. Our results confirm the usefulness of our approach compared with other well-established spatial statistical tools such as the mark correlation function.
