Maximum Likelihood Estimation of Log-Concave Densities on Tree Space
Yuki Takazawa, Tomonari Sei
Phylogenetic trees are key data objects in biology, and the method of phylogenetic reconstruction has been highly developed. The space of phylogenetic trees is a nonpositively curv…
A proper scoring rule for minimum information copulas
Yici Chen, Tomonari Sei
Multi-dimensional distributions whose marginal distributions are uniform are called copulas. Among them, the one that satisfies given constraints on expectation and is closest to t…
Improving Randomization Tests under Interference Based on Power Analysis
Mizuho Yanagi, Tomonari Sei
In causal inference, we can consider a situation in which treatment on one unit affects others, i.e., interference exists. In the presence of interference, we cannot perform a clas…
A structural model on a hypercube represented by optimal transport
Tomonari Sei
We propose a flexible statistical model for high-dimensional quantitative data on a hypercube. Our model, called the structural gradient model (SGM), is based on a one-to-one map o…
