Orthognal Regression (Deming Regression) Confidence Intervals for intercept estimates

How do you get CI's for intercept estimates using Fit Y by X>  Fit orthogonal  with eual variances....

 

i seem to just get the CIS for the slope estimate only.

You are correct. Only the confidence interval for the slope estimate is currently available.

Is that because with an orthogonal fit, the sum of squares error only estimates Y error and so that method can't be used to calculate the MSE for the orthogonal fit?

Re: Orthognal Regression (Deming Regression) Confidence Intervals for intercept estimates

Is there a way to compute the CIS for the intercept. i have just seen the CIs' in other packages for the intercept  and of course the slope)
