Hi,
Could you please help me to do the linear fitting by Origin?
Each data point for Y variable has an error bar, I would like to get the error bar for the fitted slope.
Thank you
Eric

Hi,
1> Set up the worksheet columns as X, Y, Yerr
2> Highlight Y, Yerr cols and create a scatter plot showing the error bars
3a> From Analysis menu select Fit Linear
The fit results will be in the Results log window - the standard error on slope and intercept parameters can be found there
OR
3b> Bring up the Linear Fit dialog using the Tools->Linear Fit menu item
4> Check the "Error as Weight" checkbox on Operations tab
5> Click the Fit button - again results in Results Log
