Weighted Average Formula

This version v1.0 is now displaying only the Average Customer Rating for this language which the rating was written for. It has included german and english translation. It comes out with two styles but can be easily modidied. I modified this contribution which was written Darren Grant in the...

NGRAV computes the normal gravity value (in m/sec^2 unit) of a point with the geodetic latitude defined in GRS80 ellipsoid,which is the more up-to-date and internationally adopted reference ellipsoid.The normal gravity value is used for the computation of the gravity anomaly which removes the...

The problem of fitting a straight line to data with uncertainties in both coordinates is solved using a weighted total least-squares algorithm. The parameters are transformed from the usual slope/y-axis intersection pair to slope angle and distance to the origin. The advantages of this are that...
