Dear All,
Can anyone give me the equations (or a reference) for calculating:
(a) The confidence interval for the regression line in weighted linear
regression Y=a+bX (in non-matrix form please)
I also need the equation to calculate the confidence interval for the
predicted x value (analyte concentration) from the response variable y
(instrument reading). When we estimate the x value from a linear
calibration model (again for weighted linear regression).
Please reply directly to me at [log in to unmask]
Thanks in advance for all your help
Regards.
