Extracting slope of robust fit line

rahulsmils — Sun, 11 Jun 2023 11:01:20 GMT

Hi,

I am using jsl to create an x-y plot and apply robust fit line.

I wish to extract the slope of this line in jsl to store it in an array.

I see the intercept information on the picture but the slope information seems to be incorrect.

I am not sure even if that is the slope parameter. (please see figure)

Any help would be great!

1.62 is the slope. If you Save the Predicteds, it is slope used within the formula for the predicted values. You can always check the documentation,

Thanks, I did see it was mentioned as slope. Somehow, it did not correlate well with my data in certain instances that made me curious. Anyways, thanks for confirming, I will use it for reference.
