Hi All,

there may be an easy way to do this but I haven't figured it out yet. I just want the regression line to pass through the y-axis at the intercept. So far, I can only get results like what I included in the attachment.

thanks for any help!

Solution

If you're in Bivariate, just reset the X axis to include 0 ** before** you add the Fit Line. The line will span all visible X values.

If you happen to forget to reset the axis before fitting the line...

Click the red triangle menu on the linear fit, and then select "set alpha level", 0.05 is the default so click that.

This will redraw the regression line, and it will also redraw the confidence intervals of the individual and fit too.

All you have to do to get the JMP script for this, is to generate the bivariate plot interactively, and then go to the red triangle in the output, and select "Save Script". It will give you your script for reproducing the chart.

For most of them it works fine, but sometimes when I do both the Fit

Special and the Fit Line it doesn't go to zero, but the equation still has

an intercept of zero, is there a way to fix that?

Thanks,

Tyler
