%description
Sample surveys use scientific methods to draw inferences about population
parameters by observing a representative part of the population, called
sample. The SRSWOR (Simple Random Sampling Without Replacement) is one of
the most widely used probability sampling designs, wherein every unit has
an equal chance of being selected and units are not repeated.This function
draws multiple SRSWOR samples from a finite population and estimates the
population parameter i.e. total of HT, Ratio, and Regression estimators.
Repeated simulations (e.g., 500 times) are used to assess and compare
estimators using metrics such as percent relative bias (%%RB), percent
relative root means square error (%%RRMSE).For details on sampling
methodology, see, Cochran (1977) "Sampling Techniques"
