The main idea for calibration is to use ACC data set as a source of the
household/farm size strata 2, 3 and 4 and form the survey ASS to use an
existing part, household/farm size strata 1. The ACC sampling was based on a
population census, and the ASS was based on the agricultural census plus data
from the MARDWA which is collecting from the big farm on monthly bases.
Analysing coefficients of variances and standard error of the auxiliary variables
was chosen the most suitable methods for the variable Arable Land and
Number of Farms.
Marginal tables were corrected for ratios between coefficients for the two
most important auxiliary variables.
