SYNTAX:

OFMVSTAT("Facility","Stat",Offset,Grouping, VarId1, VarId2,…VarId99)

or    

OFMVSTAT("Facility","Stat",Offset,Grouping, "Where Clause")

Facility: Facility to query against, specified by its unique identifier in quotes (e.g. "OPSWWTUTOR")

Stat: The statistic in quotes (e.g. "AVG") of the value to calculate. 

Stat	Notes
Avg	Average of values
Sum	Total of values
Max	Maximum value
Max_VarNum	Returns the Variable Number of the variable that has the maximum value.
Min	Minimum value
Min_VarNum	Returns the Variable Number of the variable that has the minimum value.
First	First value found by date
First_VarNum	The variable number of the variable that is the first value found.
Last	Last value found by date
Last_VarNum	The variable number of the variable that is the last value found.
GMean1	Returns the Geometric Mean of the values (convert 0 (zeros) to 1)
GMean2	Returns the Geometric Mean of the values (Add one to all if zero found)
GMean3	Returns the Geometric Mean of the values (Ignore zeros)
NOS,Count	Retruns the count or number of values found
PERCxx	Returns the value at the xx Percentile (i.e. PERC90).
PERAxx	Returns the value at the xx Percentile (averages two closest values if exact match not found)
PERIxx	Returns the value at the xx Percentile (interpolates two closest values if exact match not found).  NOTE: This is the technique the Excel Percentile function uses.
PERExx	Returns the value at the xx Percentile (interpolates two closest values, excludes first and last value).  NOTE:  This is the technique the Excel PERCENTILE.EXC function uses.
GTx	Returns the number of values greater than x (i.e. GT30).
LTx	Returns the number of values less than x.
EQx	Returns the number of values equal to x
NEx	Returns the number of values not equal to x.

GroupOffset/StartDate: Used with the Grouping parameter to set the dates to calculate the stat for.  Sets the number of Groups (set by the Grouping Parameter) to be added to set the dates.  See examples below. If this field is a date string (i.e. "07/16/2004") or refers to a cell with a date in it, it is assumed to be the start date to calculate the stat for.

Grouping/EndDate: Used to set which dates to calculate the stat for.  If the Grouping is a date literal string (i.e. "07/16/2004") or refers to a cell with a date in it, it is assumed to be the end date to calculate the stat for. Common Groupings are:

"D" Days
“M” Monthly 
"R" Report Dates

VarId1..VarId99: A comma separated list of variables that sets which variables to calculate from.  NOTE: This function uses VARIDs, not Varnums.   

Where clause Instead of providing a list of variables, you can use an SQL Where clause against the VarDesc table to get the list of variables.  I.E. “Units = 'mg/L'” wound return all variables with Units set to mg/L. See Examples.

 

NOTES:

To Locate this formula when designing a report, use Locate, Other Facility Group Summary or Locate, Other Facility Combined Group Summary.

EXAMPLES:

OFMVSTAT("OPSWWTUTOR", "AVG",1,"M",36)   Returns the average for the current month for variable id 36 (Varnum 4001-Effluent Flow) from the OPSWWTUTOR facility.

OFMVSTAT("OPSWWTUTOR", "MIN",1,"M",37,40)   Returns the single, minimum value for the current month for varids 37 and 40 (Varnums 4011 and 4041) from the OPSWWTUTOR facility.

OFMVSTAT("OPSDWTUTOR","MAX",1,"M","UNITS = 'mg/L'")  Returns the single, maximum value for the current month for all variables that have mg/L as units from the OPSDWTUTOR facility.
