“…Two examples are: Jones (1971, p. 367), who explored the behavior of R n across different orders of neighbors for different sorts of random and regular lattice, one finding being that the statistic appears to “converge asymptotically to the value of 2.1491 quoted by Clark and Evans … for the hexagonal case”; and Thomas (1977, p. 415), who proposed a different nearest‐neighbor statistic, based not on Poisson but rather the geometric distribution and its principle of “equal likelihood,” although he still took 2.1491 as the maximum when comparing the Clark and Evans statistic with his alternative for analyzing regular distributions based on the “equilateral triangle.” Where authors notably depart from NNA, the situation is quite different. A few, uncoincidentally from engineering backgrounds, have deployed substantially reframed species of nearest‐neighbor measures to probe an expansive “geometry” of features—“point‐like, line‐like, surface‐like”; maybe networked and amenable to representation and analysis as “graphs” or “sub‐graphs” (Pace and Zou 2000)—before addressing the implications for calculating test statistics, estimating distances to different orders of nearest‐neighbor “facilities” under differing conditions, and then practically planning for facility opening or closure (e.g., Okabe and Yoshikawa 1989; Okabe and Yamada 2001; Miyagawa 2009, 2014).…”
