      REGRESSION ANALYSIS CALIBRATION CURVE FITTING
      
      These programs calculate equations for curves obtained by plotting a graph of the values of an observed dependent variable Y for known values of the independent variable X.  i.e.  Y = F(X)
      The program can then calculate either X or Y for a given value of the other variable which is useful in instrumental analysis.
      All the curve equations created by the programs are first and second degree polynomials
 (X SQUARE)  with the general form
                         Y = A0 + A1(X) + A2(X^2)     for X <= XJ 
                                      Y = B0 + B1(X) + B2(X^2)     for  X >= XJ
             where XJ is the value of X where the 2 curve sections join together.
