TRAINING KEY 63: Design effect and allocation under stratified sampling



INTRODUCTION

In this Training Key we use the Province'91 data set as the frame population is estimating the total of the study variable UE91 (the number of unemployed in the province) by stratified sampling. In Part A, we calculate the DEFF statistic and the book example 3.1 is worked out. In Part B, different allocation schemes are demonstrated (see book example 3.2). Part C is the option for interactive analysis.



A) CALCULATION OF THE PARAMETER DEFF FOR STRATIFIED SIMPLE RANDOM SAMPLING WITH PROPORTIONAL ALLOCATION

We calculate the parameter DEFF for stratified simple random sampling (STRSRS) with proportional allocation. Further instructions will be given once you start.
 

 


B) DIFFERENT ALLOCATION SCHEMES UNDER STRATIFIED SIMPLE RANDOM SAMPLING

We examine the behaviour of different allocation schemes under ratified sampling from the Province'91 population. The population is divided into two strata, urban municipalities and rural municipalities. A stratified simple random sampling of eight elements is drawn, and the appropriate sample sizes are calculated under proportional, optimal and power allocation schemes. Further instructions will be given once you start.
 

 


C) INTERACTIVE SAS USE

Please download the SAS code for your own further training. Instructions are given in the SAS code once you download. NOTE! You need to have access to SAS in your computer.
