Figure 11-4 shows the common statistics for a uniform distribution ( ).<br />

Figure 11-4. Common Statistics for UNIF Distribution<br />

The common statistics for the uniform distribution are:<br />

• mean:<br />

• standard deviation:<br />

The half-range of the distribution is the value h = (U − L)/2. Therefore, for the following<br />

definition (using the Eldo native syntax, other syntaxes may also be valid):<br />

.PARAM PARAMETER_NAME=NOMINAL_VALUE {LOT|DEV|DEVX}/UNIF=HALF_RANGE_VALUE<br />

the value HALF_RANGE_VALUE, noted h in the formulae, represents the half range (see<br />

Figure 11-4), giving:<br />

or when this value h is specified as a percentage:<br />
