Application Guide

Curve Fit option Calculated in the form:
Power (ax^b) y=a*x^b
Exponential (ab^x) y=a*b^x
Logarithmic y=a+b*ln(x)
Sinusoidal y=a*sin(b*x+c)+d
Logistic (d 0)
y=c/(1+a*e^(-bx))+d
Natural Exponential y=a*e^(-c*x)
Proportional y=a*x
The Fit Linear dialog box opens.
4. Click OK.
5. Review the data.

Plotting a Standard or User-Defined Model
This option provides a manual method for plotting a function to fit data. Use one of the
predefined models or enter your own.
You can also set the spin increment to use in the View Details dialog box. Spin
increment is the value by which the coefficient changes when you click the spin buttons
in the View Details dialog box.
