Purpose

ParamBSpline2 A program to generate a smooth curve from sequential points in n-dimensional data. It can be used to-

• Smooth a set of data
• Insert additional points between existing points
• Reduce the number of data points
• Obtain estimates at fixed intervals
• Obtain estimates at specified points.

The program does not suffer from the most common limitations of curve fitting programs. For example:

• The data values do not need to satisfy a monotonicity requirement. In other words a given X may have more than one Y value. See the illustration below.
• The closeness of fit is controllable several ways.
• Ouput spacing is flexible.
• The program is operating system independent.

An illustration of ParamBSpline2's power is shown below, VariationInFittingParameterS.gif.
