We propose two novel logarithmic ratio–type estimators for the finite-population mean under simple random sampling without replacement (SRSWOR). The estimators integrate a logarithmic transformation ...
$$Z_{j}={\lambda}Y_{j}+(1-{\lambda})Z_{j-1},\quad for\,j= 1,2,3,...,n.$$ The variance of mean using stratified sample is given as. $$S_{{yst}}^{2}=\sum\nolimits_{{h=1 ...
