今年度は主に推定量の漸近的な性質の証明と実データ解析を行なった．証明に関しては，Biased Samplingの設定において生存時間分析のパラメトリックモデルの一致性と漸近正規性を示した．当初はセミパラメトリックモデルの漸近論の証明をする予定であったが，まずはより数学的に扱いやすいパラメトリックなモデルの漸近論に取り組んだ．また，前年度に引き続き同じ変数を持つが集団の性質や調査期間の異なる２つの政府統計データを組み合わせることで，より実態を反映した真の母平均（母集団モーメント）を推定する研究を実施し，実データを使ったデータ解析を行なった．

For this year, the principal is responsible for determining the number of people who are responsible for the analysis of business data. In this year, the main objective of this year is to determine the number of users who are responsible for the analysis of business data in the current year. In this year, the main objective of this year is to determine how much time it is necessary to determine the survival time of the database. This year, it is important to determine the accuracy of the agreement between the two systems. In the previous year, the number of data collected in the same period was the same as that in the previous year. In the previous year, the statistics of the government were in accordance with the data of the previous year. In the previous year, the statistics of the government reflected the true maternal average. Please make sure that the line is parsed.
