Glossary
The glossary offers definitions of technical terms commonly used in BIS statistics.Daily – businessweek
Similar to "daily", however there are no observations for Saturdays and Sundays (so, neither "missing values" nor "numeric values" should be provided for Saturday and Sunday). This treatment ("business") is one way to deal with such cases, but it is not the only option. Such a time series could alternatively be considered daily ("D"), thus, with missing values in the weekend.
