Frequency Data

iNZight allows users to work with frequency data, either in cases where a column contains counts/frequencies, or where the data is stored in a frequency table.

To specify frequency information, use the Dataset > Frequency tables menu.

Frequency data in iNZight.

Expand Table​

The expand table option can be used to work with both numeric and categorical variables. The storage and efficiency savings of working with a unique combinations of variables plus frequencies will typically be very much smaller here.

Specify Frequency Column​

When a frequency column is specified, graphics and summaries respond to a combinations-of-variables-plus-their-frequencies data structure. Only categorical variables are retained.

Remove Frequency Column​

This option removes the frequency column and iNZight works with the original data.
