- I have 40 (x,y) datapoints which I hypothesise form the arc of a
- circle of unknown origin and radius. I want to find an estimate
- of the radius of the circle. The preferred platform is SAS:
- I imagine proc nlin; would do it, but what is the neatest way
- to specify y in terms of x. Any suggestions on how to tackle this.
- Thanks
