STDDEV — Standard deviation
Measure dispersion around the mean.
Syntax
STDDEV(series)
STDDEV(seriesList)Inputs and results
A single series returns one number. A series list returns a one-column matrix, with one standard deviation per series in list order.
Example
x = LOGDIFF(SERIES_SINCE(INDPRO,20010101))
STDDEV(x)Notes and interpretation
This is a summary over the supplied observations, not a rolling statistic. The result uses the same units as the input. For fractional log changes, multiply by 100 to express the standard deviation in percent log-change units. No annualization is applied by this command.
