So your results mean that although the two sequences are different at... SpletNote that in addition to the distance estimates, MEGA 4 also computes the standard errors of the estimates using the analytical formulas and the bootstrap method.

Splet28. mar. 2024 · This theory, where the distance power is 2, was convenient in two respects: a) it matched accepted theories in physics, and b) it was computationally cheap. For interpolation, however, the value of 2 for the distance power is actually arbitrary. Using a value of 1 means a slower distance decay while a value of 3 means a rapid distance decay.

Some Background: Currently I'm using RPy2 to interface with R and its gstat module. Unfortunately, the gstat module conflicts with arcgisscripting which I got around by running RPy2 based analysis in a separate process.

SpletIn particular, for measuring great-circle distances on the earth or other spherical or near-spherical surfaces, distances that have been used include the haversine distance giving great-circle distances between two points on a sphere from their longitudes and latitudes, and Vincenty's formulae also known as "Vincent distance" for distance on a … Spletp-distance (Amino acids) This distance is the proportion (p) of amino acid sites at which the two sequences to be compared are different. It is obtained by dividing the number of amino acid differences by the total number of sites compared. It does not make any correction for multiple substitutions at the same site or differences in ...
