Measure of Uncertainty
An intercept table of Uncertainties is used to determine the measure of uncertainty for the analysis result. The values are shown throughout the system as +/ value after a result
Using the example above, a result of 15 is reported as 15 +/ 0.75
Calculate Precision from Uncertainties
The system also allows to calculate the precision and round the results according to the uncertainties. The rounding applies both for decimal results and results with scientific notation
The decimal position is given by the first number different from zero in the uncertainty, at that position the system will round up the uncertainty and results. For example,
 For a result 5.243 and an uncertainty of 0.22, the system will display correctly as 5.2 + 0.2
 For a value like 13.5 and an uncertainty of 1.34, the system will display correctly as 13 + 1
 For a value like 0.0077 with an uncertainty 0.0021, the system will display 0.008 + 0.002
Enabled
Exponential Format Precision value 4
 If the digits in the integer part of the result > 4, the number is formatted in scientific notation
 If the digits of the integer part of the result < 4, it is formatted as decimal notation, rounded in accordance to the precision calculated from the uncertainty

A resultsof 32092, uncertainty of 37 in range 30000  40000,
displays 3.2092E+04
A result of 5.234, uncertainty of 0.22, 1  10,
displays 5.2
Disabled
If the Calculate precision from Uncertainties is disabled for the Analysis Service, the same rules described above applies, but the precision used for rounding the result is not calculated from the uncertainty. The fixed length precision is used instead
Manual Uncertainty input
Enabling this option, will allow Analysts to manually override system calculated defaults manually, often the case in more complex Analyses
Results Options
Some Analysis Services requiring text input as results, are best limited to a number of known possible outcomes to prevent typos and irrelevant input skewing reporting
