This function deletes a first edge and makes two subsets of edges. Each
 subset is a Minimun Spanning Treee.

prunemst

A collection of functions to create spatial weights matrix
objects from polygon 'contiguities', from point patterns by distance and
tessellations, for summarizing these objects, and for permitting their
use in spatial data analysis, including regional aggregation by minimum
spanning tree; a collection of tests for spatial 'autocorrelation',
including global 'Morans I' and 'Gearys C' proposed by 'Cliff' and 'Ord'
(1973, ISBN: 0850860369) and (1981, ISBN: 0850860814), 'Hubert/Mantel'
general cross product statistic, Empirical Bayes estimates and

of spatial heteroscedasticity ('Ord' and 'Getis')
<doi:10.1007/s00168-011-0492-y>. The implementation of most of
these measures is described in 'Bivand' and 'Wong' (2018)

in linear models are provided ('Anselin et al'. 1996)
<doi:10.1016/0166-0462(95)02111-6>, as are 'Rao' score tests for hypothesised
spatial 'Durbin' models based on linear models ('Koley' and 'Bera' 2023)
<doi:10.1080/17421772.2023.2256810>.
From 'spdep' and 'spatialreg' versions >= 1.2-1, the model fitting functions
previously present in this package are defunct in 'spdep' and may be found
in 'spatialreg'.
