[R] index of dispersion

Hi list I'm looking for statisitic measurements describing the pattern of points within a given polygon. Is there a function calculating the Index of Dispersion and/or are there other functions summarising an observed pattern? Markus Schwarz

[R] Index of dispersion for counts

2005-03-22 Thread Olivier=20Gr=E9millet
Hi ! I am interrested in counting process analysis (as described in the text book of D.R. Cox the statistical analysis of series of events) and in particular in calculating index of dispersion of counts IDC(t)=Var(Nt)/E(Nt). is there some useful functions in R for such analysis ? Many thanks
