How to create and switch between datasets
It is possible to create more than one dataset through the commando
create-dataset. All operations are performed on the last dataset created (the user is automatically switched to the newest dataset). If work on a different dataset is needed, this can be done through the commando
The example below demonstrates how to create a new dataset
datasett2 and to import variables into it, and finally how to switch back to the first dataset. The dataset
demografidata contains all individuals registered with a gender, while
datasett2 only includes individuals registered with a marital status per 2010-01-01. Thus the datasets cover different populations.
Note: The first variable imported decides the population size of the specific dataset (additional variables are merged into the dataset through the left-join principle). Consequently one should not start out by importing a variable that only measures parts of the analysis population.
