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?

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)
