Curve Fitting
- CURVEFIT Bill Lurie's general purpose curve fitting routine, a la Al Rose
- CURVEFITO old curvefitting routine from Al Rose's book, replaced by W.B.Lurie
- EVALCURVEFIT test standard deviation to show how well curve fitting fits
- ALGODOMINO creates Domino algorithm (expression) for GLOBALS (B C S) per A.J.Rose
- STDDEV calculate standard deviation & variance
- CURVEFITTEST test curve fitting facility developed by Al Rose, Bill Lurie, Carl H.
- TRENDPOLY determine best fit line by regression, can project future years
- SPLINEFIT Use this function to return a series of dots that may be plotted
- SPLINECALC delivers 4 col matrix "coefficients" for spline evaluation
- SPLINEEVAL calculate regression coefficients for SPLINEFIT
- Fspline Compute Y-values for given X-values via a table of cubic splines.
- spline Compute splines through given points (n,2)½(X,Y),...
- STDDEVIATION calculate standard deviation & variance
- CDBGDECILE calculate decile distribution
- CDBGdecile next section of code calcs B= dist by income/value categories (ranges)
- CDBGincomedeciles estimate income deciles & agg. income by block for families & unr. ind.
- DECILE Create decile dist.:LA=C=Cum.Distribution, RA=B=breakpoints(top of cat.)
- DECILE910 Called in to convert 9 ele decile to 10 ele decile
- DECILETEST Developed for REGMOD, but not called, also see QUADBOARD
- PDECILE display decile distribution for the CDBG facility (only use so far)
- UNDECILE Converts decile distribution IS to arbitrary categories specified as RA
