The procedure is then

1. Generate list of d(observed)

2. Sort list di, i = 1, n

3. Calculate fractional rank index r = |n-2i+1|/n

4. Look up in cumulative normal probability table the value of x such that P(x) = r

P(x) = (1/v2p) -x ? x exp (-a2/2) da

Set d(calculated) = x

5. Plot d(observed) against d(calculated)
