pysal.explore.spaghetti.NetworkF

class pysal.explore.spaghetti.NetworkF(ntw, pointpattern, nsteps=10, permutations=99, threshold=0.5, distribution='poisson', lowerbound=None, upperbound=None)[source]

Compute a network constrained F statistic. This requires the capability to compute a distance matrix between two point patterns. In this case one will be observed and one will be simulated.

Attributes:
fsim : spaghetti.network.SimulatedPointPattern

simulated point pattern of self.npts points

Methods

computeenvelope() compute upper and lower bounds of envelope
computeobserved() compute the observed nearest and simulated nearest
computepermutations() compute permutations of the nearest
setbounds(nearest) set upper and lower bounds
validatedistribution() enusure statistical distribution is supported
__init__(ntw, pointpattern, nsteps=10, permutations=99, threshold=0.5, distribution='poisson', lowerbound=None, upperbound=None)

Initialize self. See help(type(self)) for accurate signature.
