CurveReg - Regression curve
Interpolation of an optimized regression curve through a set of points
This online regression curve generator uses various calculation methods like Least-squares, Deming, WLS or LOESS to generate an optimized line or polynomial curve (2nd-10th order) or general curve from a given set of 2D X-Y points.
Paste the point coordinates from Excel via clipboard or by dropping a CSV or XLS file, then select the regression algorithm and select the order of the generated curve. The resulting regression curve can be exported to a DXF file as LINEs or a POLYLINE entity, or to an AutoCAD script as a LWPOLYLINE or SPLINE (requires JavaScript)
