In usual stratified design, it is assume that strata sizes are known
as well as strata frames
are also available. When frames are unknown the
post-stratification is only solution. Agrawal and Panda (1993)

mail survey design under the nonresponse
and proposed a PSNR strategy for estimating the population mean.
response between strata

has no response but the strata
generates cent-percent response. This pattern. if priory
known. could be utilized
in estimation strategies. This paper exploits information of response pattern and presents PSNR sampling scheme with
of strata under the
of complete response
and complete nonresponse. An estimation strategy is constituted for the population
and its variance is derived.
