if sigma2_v1 is True: only use n-tr(S) in denominator
Methods: p214, (9.6), Fotheringham, A. S., Brunsdon, C., & Charlton, M. (2002). Geographically weighted regression: the analysis of spatially varying relationships.

if sigma2_v1 is False (v1v2): use n-2(tr(S)+tr(S’S)) in denominator
Methods: p55 (2.16)-(2.18) Fotheringham, A. S., Brunsdon, C., & Charlton, M. (2002). Geographically weighted regression: the analysis of spatially varying relationships.
