  Bohm's theory involves parameter dependence and thus controllable probabilistic dependence: The probabilities of distant outcomes depend on the setting of the nearby apparatus. In some pairs' states λ, i.e., in some configurations of the positions of the particle pair, a change in the apparatus setting of the (earlier) say L-measurement will induce an immediate change in the probability of the R-outcome: e.g. the probability of R-outcome z-spin ‘up’ will be 1 if the L-apparatus is set to measure z-spin and 0 if the L-apparatus is switched off (see section 5.3.1). Thus, the question of superluminal signaling turns on whether λ-distribution obtains.
