WebW = ∑ i = 1 n ( X i − μ σ) 2. Now, we can take W and do the trick of adding 0 to each term in the summation. Doing so, of course, doesn't change the value of W: W = ∑ i = 1 n ( ( X i − X ¯) + ( X ¯ − μ) σ) 2. As you can see, we added 0 by adding and subtracting the sample mean to the quantity in the numerator. WebF Distribution Deﬁnition. For independent r.v.’s U and V where. U ∼ χ. 2. m. V ∼ χ. 2 n.
