Pearson-Fisher Chi-Square Statistic Revisited

The Chi-Square test (χ 2 test) is a family of tests based on a series of assumptions and is frequently used in the statistical analysis of experimental data. The aim of our paper was to present solutions to common problems when applying the Chi-square tests for testing goodness-of-fit, homogeneity and independence. The main characteristics of these three tests are presented along with various p...

The Absence of Hepatitis C Virus Infection Among Patients with Hepatitis B virus in Mashhad, Iran

Background and Aims: Many studies have provided evidence for the role of hepatitis B and C viruses in the development of liver cancer. Although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with HBV and HCV. This study was performed to determine the frequency of HBV/HCV-coinfection in Mashhad, North-East of Iran. Mat...

Mining Statistically Significant Substrings using the Chi-Square Statistic

The problem of identification of statistically significant patterns in a sequence of data has been applied to many domains such as intrusion detection systems, financial models, web-click records, automated monitoring systems, computational biology, cryptology, and text analysis. An observed pattern of events is deemed to be statistically significant if it is unlikely to have occurred due to ra...

Mining Statistically Significant Patterns using the Chi-Square Statistic

Statistical significance is used to ascertain whether the outcome of a given experiment can be ascribed to some extraneous factors or is solely due to chance. An observed pattern of events is deemed to be statistically significant if it is unlikely to have occurred due to randomness or chance alone. In the thesis, we study the problem of identifying the statistically relevant patterns in string...
