Newspell
NEWSPELL is a program that allows the manipulation of Spell files. One can use it for any of the following:
- Create distinctive calendars and eliminate multiple cites with a user defined hierarchy. For example, in the Spell file ARTKALEN.DAT (Occupation calendar on monthly basis) one can define a priority of spell information in case of multiple cites in such a way, that the event "unemployment" is picked over any other response given for the same time period.
- Aggregation of events. Different events can be combined within a single Spell type. For example the occupation status "Full-time Employment" and "Part-time Employment" can be combined into a single Spell type "Gainful Employment".
- Disaggregation of combined events. For example the events "Full-time Employment" and "Unemployment" can be split into three different categories, depending on their occurrence in a given time period of interest (month or year):
- Type 1: Unemployed and full-time employed at the same time
- Type 2: Unemployed but not full-time employed at the same time
- Type 3: Full-time employed but not month unemployed at the same time
- The output can be selected as a new Spell file with censor information and/or as time series data.
- Additionally, a log-file keeps record of all activities of a session with NEWSPELL.
- A result file contains frequencies of each new spell type for each person.
