Curve Fitting - Regression Software
Chemistry
Software Download
Fitting a curve to an (x,y) data set in the CHEMIX School program is
quite
simple, just insert your x,y data in the Data (x,y) edit field and
select
Best fit. By using the Best fit option a function
representing
the best correlation will be selected automatically and a curve will be
plotted.
It is also possible to manually select/fit/plot a function -
simply
select a function by clicking on it. Other options in CHEMIX School
are:
spline interpolation, calculate definite integrals, plot
derivatives and the ability to manipulate data. By the
copy
to clipboard option ,a bitmap of the figure/plot can be pasted
into other
(paste enabled) applications such as word processors etc.
In CHEMIX School following functions can be fitted
to x,y data.
Y = A + B*X , Y = A + exp(B*X) , Y=
A*X^B , Y = A
+ B*ln(X) , Y = A/X + B , Y = (A + B*X)/(1 +
C*X)
, Y = A + B*X + C*X^2 (polynome), Y = A
+
B*X + C*X^2 + D*X^3 (polynome)
CHEMIX School also contain a Scientific Calculator, Ternary phase
diagrams
and much more - Try it.
