Spreadsheet Formulas - Row, Column Functions
Statistica provides a predefined broad selection of row and column functions that can be used in spreadsheet formulas like all other functions. Following is a list of all available row and column spreadsheet functions (parameters are given in parentheses).
| CaseName | CaseName | Return the case name of the current case |
| Cusum | Cusum(vref [, offset]) | Returns the cumulative sum of the variable vref from case 1 thru the current case. If 'offset' is provided, this value is subtracted from the variable value before adding to the running total. |
| Data | DATA(vref, row) | Returns the value from a specified spreadsheet cell. For example: The following will fill current variable with whatever variable 3 has in row 2: = DATA(V3, 2) The following will create a Fibonacci series: =iif(V0 <= 2, 1, DATA(VCUR, V0-1) + DATA(VCUR, V0-2)) The following produces a cumulative sum of variable V3: =iif(V0 <= 1, V3, DATA(V3,V0) + DATA(VCUR, V0-1)) NOTE: If the variable-ref is to be computed or an absolute index is needed, use VREF as in DATA(VREF(1), V0). |
| Dif | DIF(vref, offset) | Returns the difference between the current value of variable vref and its value in the current row less offset. For example (when applied to Variable V3): =DIF(V3, 3) Is equivalent to =V3 - LAG(V3,3) |
| Lag | LAG(vref, offset) | Returns value of variable vref in the current case less the offset. For example: =LAG(V3, -3) =LAG("MEASURE01", V2) The following will perform a cumulative sum of V3: =iif(V0 <= 1, V3, V3+LAG(VCUR, 1)) |
| NCases | NCASES | Returns the number of cases in the current spreadsheet. For example: The following will fill the current variable with the inverse order of what is in V3 =DATA(V3, NCASES-V0+1) |
| NVars | NVARS | Returns the number of variables in the current spreadsheet. For example: The following will always reference the last variable in the file: =VREF(NVARS) |
| SelCond | SelCond | Returns true if the current case is selected by the attached selection conditions (or if there are no such conditions) |
| V0 | V0 | Number of currently processed case |
| VCUR | VCUR | Refers to the current variable, e.g., in a spreadsheet formula for variable 3, VCUR is equivalent to V3. Return the current variable number being processed. It is useful to make formulas more portable. For example: =VCUR + 1 If applied to V3, then this will add one to V3, and would be equivalent to =V3+1. |
| VRef | VREF(column_number) | Convert the numeric argument to a variable reference with value of that variable in the current row. For example: Example: =VREF(2) Is equivalent to =V2 The power of is that it can evaluate at runtime. For instance: =VREF(V3) |
| Vxxx | Vxxx | Statistica data file variable xxx, e.g., V2 is variable 2. Statistica variables can also be referenced by name. |
