2024年1月1日 · A new banded time-varying precision matrix estimator is proposed for high-dimensional time series. The estimator utilizes the modified Cholesky decomposition, and the two factors in the decomposition are dynamically estimated by applying the GARCH model to the innovation variance and the Kalman filter on the Cholesky factor.

Objective: To compare the long-term dentoskeletal effects of early treatment with banded or bonded RME (Rapid Maxillary Expansion)-Face Mask (RME-FM) versus late treatment with bonded Hybrid-Hyrax, alt-RAMEC (Alternate Rapid Maxillary Expansion and Contraction) and intraoral Class III elastics anchored to miniscrew-reinforced-Lower-lingual-Arch ...

2015年1月1日 · In this chapter, we present parallel algorithms for solving narrow-banded linear systems: (a) direct methods that depend on elimination with partial pivoting as well as pairwise pivoting strategies, (b) a class of robust hybrid (direct/iterative) solvers for narrow-banded systems that do not depend on a global LU-factorization of the ...

2023年7月16日 · 首先该检验实际为卡方检验，因此本质需要 二分类变量。 在此举例。 如你的原表格为发病率和总人数，这时候必须要转换为二分类表格。 我们将1定义为发病，2定义为不发病。 那么我们将重新整理得到如下表格。 接着将它粘贴到SPSS里，如下定义。 其中需要注意的是，类型全部为数值！ 否则将无法分析。 接着选择数据-》 加权个案. 把fre进行加权个案，点击确定。 紧接着，选择分析-》描述统计-》 交叉表格 -》将行和列分选选为年和是否发病-》选择statistics- …

Mandibular expansion is achieved using a lower lingual arch (LLA). Bands with horizontal lingual sheath are cemented to the permanent first molars, and a removable 0.030” lingual arch∗∗ is inserted into the sheaths to expand these teeth.

This study compared the long-term dentoskeletal effects of early treatment with banded or bonded RME-FM versus late treatment with bonded Hybrid-Hyrax, alt-RAMEC-HH-LLA in growing, maxillary retrognathic patients.
