Calculating Sample Variance for the Combined Data

Autor: Mi Young Shin, Tae-Kyoung Cho

Publikováno v: Korean Journal of Applied Statistics. 21:177-182

There are times when we need more sample to achieve a more accurate estimator. Since these two sets of sample have the information about the same population, it is necessary to treat both as a single combined data. In this paper we present the unpool

Relationship Between the Mean and Median in a Skewed Frequency Distribution

Autor: Tae Kyoung Cho, Mi Young Shin

Publikováno v: Communications for Statistical Applications and Methods. 11:513-518

The well-known mode-mean-median inequality for the unimodal population distribution does not always hold for the frequency distribution. But many elementary statistics text books just mention that the relative location of the mean and median can be u

The Confidence Intervals for Logistic Model in Contingency Table

Autor: Tae-Kyoung Cho

Publikováno v: Communications for Statistical Applications and Methods. 10:997-1005

We can use the logistic model for categorical data when the response variables are binary data. In this paper we consider the problem of constructing the confidence intervals for logistic model in IJ2 contingency table. These constructions are simpli
