Symmetry of scale

The term used in the stochastic literature for these models is intrinsic random fields (IRFs) they appear under that name in textbooks of geostatistics (e.g. Cressie, 1991 Chiles and Delfiner, 1999). This chapter also introduces the intrinsic warps (IWs) intended to replace my principal and partial warps of 1989 for data analysis of landmark-like configurations under symmetries of scale. These IWs could well implement the movable potentially homologous characters that may someday underlie computer-assisted algorithms for stable ordinations or ecophenotypy surveillance much better than existing techniques could likely do.
