Prognosis-equivalent mapping of clinical measurements via survival analysis
Kazuharu Harada, Mitsunori Ogawa
A continuous clinical measurement recorded in fixed physical units may have different prognostic meaning across patients when its effect depends on a patient-level modifier. For ex…
Non-asymptotic goodness-of-fit tests and model selection in valued stochastic blockmodels
Félix Almendra-Hernández, Miles Bakenhus, Vishesh Karwa +2
A valued stochastic blockmodel (SBM) is a general way to view networked data in which nodes are grouped into blocks and links between them are measured by counts or labels. This fa…
Existence of Firth's modified estimates in binomial regression models
Mitsunori Ogawa, Yui Tomo
In logistic regression modeling, Firth's modified estimator is widely used to address the issue of data separation, which results in the nonexistence of the maximum likelihood esti…
Markov degree of configurations defined by fibers of a configuration
Takayuki Koyama, Mitsunori Ogawa, Akimichi Takemura
We consider a series of configurations defined by fibers of a given base configuration. We prove that Markov degree of the configurations is bounded from above by the Markov comple…
Markov degree of the Birkhoff model
Takashi Yamaguchi, Mitsunori Ogawa, Akimichi Takemura
We prove the conjecture by Diaconis and Eriksson (2006) that the Markov degree of the Birkhoff model is three. In fact, we prove the conjecture in a generalization of the Birkhoff…
Markov Bases for Typical Block Effect Models of Two-way Contingency Tables
Mitsunori Ogawa, Akimichi Takemura
Markov basis for statistical model of contingency tables gives a useful tool for performing the conditional test of the model via Markov chain Monte Carlo method. In this paper we…
