To make use of a beneficial spatial selection method, a grid regarding estimation facts is placed around the for every MSA, and a curved filter increases, according to a selected tolerance, discover study out of numerous census tract centroids up until a constant fact is actually estimated for each and every grid part playing with logistic regression patterns given for every HMDA level. New figure try mapped once the a continuing surface playing with an inverse distance weighting strategy. Just like the methods are continually laid out, he is effortlessly described by the different varieties of limitations. This is really important, just like the HOLC boundaries established in the fresh new 1930s do not correspond to any current management limits.
