Post-test-only functions and formulas
A formula containing any one (or more) of the remaining Formulator functions is a post test only
formula. It executes only at the end of each run of the ITM or UTM in which the formula is defined.
The results of a post test only formula may be viewed in the Sheet tab Data worksheet or plotted
only at the end of a test.
The following functions are post test only functions:
AT, AVG, COND, EXPFIT, EXPFITA, EXPFITB, FINDD, FINDLIN, FINDU,FIRSTPOS, LASTPOS,
LINFIT, LINFITSLP, LINFITXINT, LINFITYINT, LOGFIT, LOGFITA, LOGFITB, MAVG, MAX,
MAXPOS, MIN, MINPOS, REGFIT, REGFITSLP, REGFITXINT, REGFITYINT, SUBARRAY,
SUMMV, TANFIT, TANFITSLP, TANFITXINT, TANFITYINT
The formula below is a post test only formula, because MAVG is a post test only function:
•
Post test only formulas execute as follows:

• If a post test only formula is created before the ITM or UTM has been run, the formula
executes automatically at the conclusion of each run.
• If post test only formula is created after an ITM or UTM has been run, the formula executes
initially upon adding it to the UTM or ITM and automatically at the conclusion of each
subsequent run.
Open the Definition tab for the test data that you wish to analyze by clicking on the
appropriate ITM or UTM in the Project Navigator. The Definition tab appears.
In the Definition tab, click on the Formulator button. The Formulator window opens. See
Figure 6-358.
