Inconsistency of diagonal scaling under high-dimensional limit: a replica approach
Tomonari Sei
In this note, we claim that diagonal scaling of a sample covariance matrix is asymptotically inconsistent if the ratio of the dimension to the sample size converges to a positive c…

Infinitely imbalanced binomial regression and deformed exponential families
Tomonari Sei
The logistic regression model is known to converge to a Poisson point process model if the binary response tends to infinitely imbalanced. In this paper, it is shown that this phen…
