cfetoolupdate(8) Update the database with a new value

OUTPUT

Before exiting, "cfetool update" will print one line to the standard output stream in the following format:

yrly=ynum,wkly=wnum,dly=dnum

ynum, wnum and dnum will be either the number 0 if the corresponding database was not updated, or a code indicating the state of the given statistic, as compared to an average of equivalent earlier times, as specified below:

 code    high|low|normal   meaning
 -------------------------------------------------------------
  -2     -                 no sigma variation
 -------------------------------------------------------------
  -4     low               within noise threshold, and within
  -5     normal              2 standard deviations from
  -6     high                expected value
 -------------------------------------------------------------
 -14     low               microanomaly: within noise
 -15     normal              threshold, but 2 or more standard
 -16     high                deviations from expected value
 -------------------------------------------------------------
 -24     low               normal; within 1 standard deviation
 -25     normal              from the expected value
 -26     high                
 -------------------------------------------------------------
 -34     low               dev1; more than 1 standard 
 -35     normal              deviation from the expected
 -36     high                value
 ------------------------------------------------------------
 -44     low               dev2; more than 2 standard
 -45     normal              deviations from the expected
 -46     high                value
 -------------------------------------------------------------
 -54     low               anomaly; more than 3 standard
 -55     normal              deviations from the expected
 -56     high                value

Where ``low'' indicates that the current value is below both the expected value for the current time position, and the global average value. ``high'' indicates that the current value is above those values. ``normal'' indicates that the current value is within the range of expected values.

"cfetool update" also exits with a code corresponding to the above table. If more than one database is being updated, the most negative result from the updates is returned, and the individual results must be obtained from the standard output stream, as described above.
