ISmCensus2.NormDailyWeights

Syntax

NormDailyWeights: Array;

Description

The NormDailyWeights property returns normalized weights for weekdays.

Comments

The sum of normalized weights for weekdays is 7, if values of ISmCensus2.DailyWeights include at least one non-zero value.

Example

To execute the example, add a link to the Stat system assembly.
