I have variable 'X' for which I know only the MEAN value along with 16th and 84th percentile of its PDF.
Now this variable (X) is used in another variable calculation (let's say 'Y') for which I have to provide an absolute error limit. (let's assume Y=constant1 * X + Conatant2).
Is there a way to give absolute error estimate over calculated values of 'Y'.
Note: I am not a math expert so have no idea about the level of this question.
