Z-Score

4 906
The z-score is a way of counting the number of standard deviations between a given data value and the mean of the data set.

Z-score = (x̄ - μ) / (σ / √ n)

x̄ = sample mean (using the array.avg function = array(a,close), where i = 1 to 21)
μ = population mean ( = avg(close, n))
σ = standard deviation of the population ( = stdev(close,n))
n = number of 'close' or trading day closes

n = input

... Note: The previous indicator is part of a larger series of indicators [statistical analysis of time series]
