It can't be since θ is not local-realistic.lugita15 said:Yes, P(θ) is the local hidden variable that determines the individual detection results.
Consider a setup where settings a and b are determined immediately before the measurement A and B by sampling polarization of photons coming from distant stars and detectors A and B are some distance apart and in relative motion. Thanks to relativity of simultaneity, it can be arranged so that in reference frame of A, measurement of A happens before the photon determining b hits the target, and vice versa, in reference frame of B, measurement B is done before a is determined. So from the point of view of either detector θ does not yet exist when the measurement is done. Therefore the results of the measurement cannot be determined by θ or any function of θ, not in local-realistic sort of way.
