the value of the weight . Also using ( | , ) = ( | , ) and
( | , ) ≈ from Pfeffermann and Sverchkov (2003) and obtained by
substrata, we can construct the following model.

3. Estimation of bias on a linear non-response rate model
a. Sample distribution and bias estimation
In this study we consider the error of the super population model follows
the normal distribution and the population distribution is given by (2). Also,
we consider the linear response rate model as follows.

Then simply we have the following result.

Now, using the equations (6) and (7), we get the following result.

Now let ( | ) be a distribution of ( | ). Then it becomes simply the
