The purpose of this project was to develop computer application software to estimate parameters in double sampling design. Double sampling or two-phase sampling is used in a wide variety of surveys which includes situations of non-response, missing data, populations that are rare, remote or hard to access, sampling at multiple occasions and in quality control studies. Application software was developed using C++ programming language whereby the formulae used in these different applications were in-built in the system to enable easy computation of parameters for the different well-known applications like double sampling for stratification, double sampling for ratio estimation, double sampling for regression estimation, optimum allocation and repeated sampling of the same population.
