Old Technical Reports
- Improving predictive inference under covariate shift by weighting the log-likelihood function, ISM RM-712, 1998. This technical report is almost the same as the first paper of “covariate shift” adaptation (Shimodaira JSPI 2000), but its geometrical argument in Section 8 has been deleted when published.
- A graphical technique for model selection diagnosis, ISM RM-680, 1998. A part of this technical report is included in a paper (Shimodaira Comm. Stat. 2001) published later.
