Removing units from a dataset
In order to perform statistical analysis on a dataset, there is often a need to trim the dataset by removing unwanted units. This can be done by using the commandos
keep in combination with standard IF-conditions.
In the example below, the data population is trimmed into persons between 16 and 66 years of age.
create-dataset demografidata import BEFOLKNING_KJOENN as kjønn import BEFOLKNING_FOEDSELS_AAR_MND as faarmnd generate alder = 2010 - int(faarmnd / 100) keep if alder >= 16 & alder < 67
