It is not really z scores, the transformation involves ranking the observations, then the ranks are being substituted by scores on the normal distribution. The scores are from the normal distribution by dividing the distribution into the number of observations plus one regions on the basis that each region has equal probability. For example, if there are six observations the normal distribution would be divided into seven equally probable parts so that the original value are replaced by normal scores (here -1.0676, -0.5659, -0.1800, 0.1800, 0.5659, 1.0676) rather than the ranks 1,2.....,6.

series z = @qnorm(@ranks(x)/(@obs(x)+1))
