the Bugsystem includes several ensemble operators which compute a statistic 
(e.g., an estimate of the mean or mean vector or even a histogram) for every 
frame defined within the operand data. The Bugsystem also includes serial 
correlation operators (viz., AUTOCORRELATION and CROSS 
CORRELATION). Programs providing for analysis in the frequency domain, 
sinusoidal, regression and polynomial regression are currently under 
development.
