type

algorithm used to sample from original microdata. Currently supported choices are

n_perc

the restricted microdata will be a n-percent sample of the original microdata.

first_n

only the first n observations will be used.

every_n

the restricted microdata set consists of every n-th record.

size_n

a total of n observations will be randomly drawn.
