Genetic Network Inference Using Hierarchical Structure

Shuhei Kimura, Masato Tokuhisa, Mariko Okada-Hatakeyama
2016 Frontiers in Physiology  
We take this step using an existing method that combines a genetic network inference method with a bootstrap method.  ...  The improvement accomplished by the use of the hierarchical structure is small. However, the hierarchical structure could be used to improve the performances of many existing inference methods.  ...  The method proposed in this study, on the other hand, searches for them using multiple genetic networks inferred by the bootstrap approach.  ...

Shuhei Kimura, Koji Kitazawa, Masato Tokuhisa, Mariko Okada-Hatakeyama
2017 Chem-Bio Informatics Journal  
The framework uses a priori knowledge only to modify the genetic network that has already been inferred by the other inference method.  ...  Yet the genetic networks inferred by these methods often contain large numbers of false-positive regulations along with the true-positives.  ...  Acknowledgements This work has been supported by JSPS KAKENHI Grant Number 26330275.  ...

The Apportionment of Total Genetic Variation by Categorical Analysis of Variance

Tsung Fei Khang, Von Bing Yap
2010 Statistical Applications in Genetics and Molecular Biology  
This method potentially challenges researchers to rethink conclusions derived from a well-known method known as the analysis of molecular variance (AMOVA).  ...  We wish to suggest the categorical analysis of variance as a means of quantifying the proportion of total genetic variation attributed to different sources of variation.  ...  The SSBR is computed by complementation. The parameters of interest can be similarly found using methods in Section 3.1.  ...
