Curve Fitting 97 Parameters order Set the maximum order of the polynomial. regcoef Returns the calculated curve fit coefficients. The coefficients are returned in an array, elements [0] to [order]. regstats Returns curve fit statistics. Return Value Returns an error code. RegStats class Public Instance Properties ovfst r rsq see sigflag sumressq Get/Set overall F statistic Get/Set multiple correlation coefficient (Rvalue) Get/Set coefficient of determination (RSquared) Get/Set Returns the Standard error of estimate ( Get/Set significance of regression flag Get/Set sum of residuals squared Method CurveFit.exponentialSolve This method fits the data to an exponential equation of the form: y = aebx. The exponentialSolve method returns the solution coefficients a and b in the equation above. All values of y must be positive. public int exponentialSolve ( DDMat regcoef, RegStats regstats ); Parameters regcoef Returns the calculated curve fit coefficients. The (a) coefficient is returned in the array element [0] and the (b) coefficient is returned in the array element [1].
