WebDec 1, 2005 · The first simulation study demonstrates two important results: pairwise ML distances provide equally good distance estimates as patristic ML distances to the DistR method ; if the fit of the initial pairwise/patristic ML distances to the data is accurate then the DistR estimates will be accurate (Figs. 3 and 4). WebJun 15, 2024 · So from individual #1 to individual #18, it is 325 cm, etc. Which produces a graph (although I cannot post it). My question is: Given the distances between some of the points, is there a way to calculate pairwise, linear distances for all points? I didn't collect any data on geo-referenced coordinates, although I believe it might be necessary to assume …
