Problem about the parameters in Bayesian estimation

Hi everyone,

I’m confused with one problem about the parameters in Bayesian estimation.

When using Bayesian method to estimate the model(linear model) parameter A, other parameters depend on A should also change with the estimation result of A. However, the mat file after estimation shows that they did not change with A.
Example: A=2;B=A-1(=1);
after Bayesian estimation, A becomes 0.8, but B still equals to 1.
I’m afraid whether it will affect the estimation result of A? If so, how can I avoid this problem?

Thank you in advance!

It’s most probably:
