Curve Fitting
The Main Steps Of Operation:
To implement curve fitting, following these steps:
1. Input your data in Data Editor.
2. Select Stats -> Regression -> Curve Fitting... from the menus.
3. Select variables and models in Curve Fitting dialogbox, and click OK button.
Models:
Visual Stats provides ten models. The following table shows the names and functions of these models.
Name |
Model |
| Linear |
y=a*x+b |
| Inverse(1) |
y=a/x+b |
| Inverse(2) |
y=1/(a/x+b) |
| Logarithmic |
y=a*ln(x)+b |
| Exponential |
y=exp(a*x+b) |
| XY Logarithmic |
y=exp(a*ln(x)+b) |
| S |
y=exp(a/x+b) |
| X Root |
y=a*sqr(x)+b |
| Y Root |
y=(a*x+b)^2 |
| XY Root |
y=(a*sqr(x)+b)^2 |
