Fórmulas
P(y|x) = P(x,y)/P(x)
s2x = Σ(x-x̄)2f(x)
s2y = Σ(y-ȳ)2f(y)
sx,y = Σ(x-x̄)(y-ȳ)f(x,y)
rx,y = sx,y/(sxsy)
Ejemplo
Entrar n Px(j) valores (en cualquier unidad coherente, separar cada valor con una coma): [Px (j, k) = Py (j, k) ]:
Entrar n2 Px,y(j,k) values (j que varía primero, k que varía en segundo lugar; separe cada valor con una coma) La suma de Px,y (j, k) los valores deben ser iguales 1]:
