As the needs of utilizing the privacy information such as giving the receipt to researchers in the university for
the development of medical care are emerging, an advanced anonymization technique such as k-anonymity and a statistical analysis for anonymized data are recently studied. In this research, we focus on the student's t-test which is a highly important statistical test, and show how to perform the t-test of the perturbed data. Though in the past the statistical results of anonymized data has no guarantee, using our proposed method, one can perform the statistical analysis of anonymized data where this analysis has the same level of confidence compared to that of analyses of the original data with student’s t-test. And it may be possible to use the analysis where a higher reliability is needed, such as an epidemiological study. |
