I have the surrogate function of the input and output. with the input follow the uniform distribution.
I have input: x = uniform distribution (0,1)
the surrogate function of input and output: y = 2.3 x^4-9.8x^3+15.2x^2-10.334x+2.7 ( where x is the input, and y is the output)
how to apply Bayesian method to find the posterior distribution?
