ある定点(焦点)を通るm本の回帰直線群を推定するモデルについて議論する。この焦点は観測状況や実験条件に依存して動く点であり,回帰直線のパラメータと同時に推定する必要がある。基礎となる2つのモデルについて,最小2乗法あるいは対数尤度の最大化に基づき,未知のパラメータを推定する。得られたモデルの妥当性を数値的に検証し,実データへの応用を試みる。

A dataset that contains missing regions is assumed to arise from two or more populations. In order to decompose the data into meaningful component distributions, a normal mixture model can be applied. A problem with this approach is that the estim...
