Least Squares Line Calculator

Calculate a least squares line fitted solution to a set of points stored on your device's storage. App scans for, and displays only PNEZD (comma delimited file - Point Number, Northing, Easting, Elevation, Description) formatted text files placed on your device. Each file should contain only those points to be least squares line fitted. After initial calculation, change weight of any point, or choose to include / exclude any point, and recalculate. List shows perpendicular offsets to calculated line, weighting of each point, and if the point has been included in the solution. Display above list shows endpoint coordinates, as well as, the bearing and distance of the line.
