      Abstract
      If the sample is taken by using multistage random sampling, through reducing sample size in the next stage, then the ordinary logistic models can’t be used. This data will be analyzed using logistic models with the additional intercept. This research studied the application of addition intercept terms in logistic regression for case control study used multi stage random sampling. Furthermore, this research compared between the model which was formed and the model of the frame sampling data. The addition intercept in logistic models was able to describe the pattern of relationship explanatory variable with response variable. Missing information decreases with increasing number of samples that observed. Average of missing information in the third stage tends to be smaller than in the second stage, because the third stage has more homogeneous sample units than the second stage. The average of missing information is smaller than the average reduction in the number of samples when using multi-stage random sampling, so this sampling technique is also suitable for use in research aimed at predicting the probability of case. Moreover the use of the sampling technique can reduce the sampling cost.
       
      Rancangan penelitian yang banyak digunakan dalam bidang epidemiologi adalah rancangan penelitian kasus-kontrol. Dalam penelitian kasus-kontrol, contoh kasus dan contoh kontrol diambil secara terpisah. Kasus merupakan unit contoh yang memiliki karakteristik tertentu yang diamati, sedangkan kontrol merupakan unit contoh yang tidak memiliki karakteristik tertentu yang diamati. Teknik pengambilan contoh dengan beberapa tahap dapat digunakan untuk mengambil contoh kasus dan kontrol. Manfaat lain dari penggunaan teknik pengambilan contoh dengan beberapa tahap yaitu dapat mengurangi biaya pengambilan contoh. Hal ini mungkin terjadi apabila penelitian memiliki biaya pengamatan suatu peubah lebih mahal dari peubah yang lain. Dengan menggunakan teknik pengambilan contoh dengan beberapa tahap, peubah yang memiliki biaya pengamatan yang mahal diamati di tahap terakhir pengambilan contoh dan hanya sebagian yang diamati.
