TRAINING KEY 117: Reweighting



INTRODUCTION

A) REFERENCE EXAMPLE 4.2: SAS CODE AND OUTPUT

Techniques for adjusting to unit nonresponse are worked out in this Training Key by reweighting for an SRSWOR sample drawn from the Province'91 population. The methods include reweighting by the response homogeneity group method and ratio estimation. In addition, accounting for the extra variation because of reweighting is illustrated in variance estimation of a HT estimator of the total of UE91.
 

 


B) INTERACTIVE SAS USE

Please download the SAS code for your own further training. Select your own sample or several samples and exercise reweighting with different sample sizes for a SRSWOR sample. The macro parameters used in the application are DATA=data, n = sample size and SEED = seed for the random number generator. You may choose 1 < n < 32 elements in the sample and by changing the seed different sample configuration will be obtained.

NOTE! You need to have access to SAS in your computer.
