Purpose
This app can be used to:
- Compare slope and intercept across multiple datasets.
- Compare multiple datasets using a linear model.
Installation
Download the file "Compare Linear Fit Parameters and Datasets.opx", and then drag-and-drop onto the Origin workspace. A "Compare Linear Fit Parameters and Datasets" icon will appear in Origin's Apps panel.
Operation
- With a worksheet or graph active, click the "Compare Linear Fit Parameters and Datasets" icon from the Apps panel to open the dialog. The Settings node provides option for comparing datasets or comparing parameters. This node also provides two options for method: Akaike Information Criteria(AIC) and F-test. If there are more than 2 datasets, it allows to compare datasets pairwise if there is difference among all datasets.
- When the dialog is open, click the ? button on the top-right corner, or press F1 to open the help file, which includes explanation of the dialog settings and an example.
