Simple complementarity forbids the existence of such joint probability distribution. Moreover, the measurement of incompatible observables requires different experimental procedures, which no necessarily must share a common joint statistics. In this work, we avoid these difficulties by proposing a joint simultaneous measurement. We can obtain the exact individual statistics of all the observables involved in the Bell inequalities after a suitable data inversion. A lack of positivity or any other pathology of the so retrieved joint distribution is then a signature of nonclassical behavior.engjournal articlehttp://dx.doi.org/10.1016/j.physleta.2020.126416https://www.sciencedirect.comopen access535VariablesÓptica (Física)2209.19 Óptica Física
