As you bring data into dataZoa, it is harmonized (or "normalized") so that any series can work with any other. While we preserve all the original series documentation, we load the dates and values into an idealized time series. This automatically handles the specific nuances of time series data, elimination the "data drudgery"; cleaning, aligning, pasting, re-typing and such.

Data Value Handling

Missing Values Handling

Values can be "missing" for different reasons, with different implications. dataZoa recognizes several different types of missing values and treats them appropriately.

Formal specifications are here.

Calculations

In all calculations, missing data has the highest precedence; e.g. a number plus an NA yields an NA. Specialized functions in the ComputeCloud can be used for specialized handling, such as carry-forward, etc.

Tables

By default, No Data (ND) formats as a blank, while NA, and NDD data are formatted with "NA" and "NDD", respectively. To fine tune these representations, see Displays.

Charts

Missing values are typically shown as gaps.
