On the sample sizes of one-stage and two-stage sampling procedures under heteroscedasticity
, 2011 碩士在檢定母體平均數是否相等的變異數分析方法中，其基本假設是模型誤差項為獨立的常態分布、和有相等變異數。當變異數未知且不相等時，Bishop and Dudewicz (1978) 導出二階段抽樣程序方法，而 Chen (2001) 提出一階段抽樣程序方法，分別用來檢定是否有相同的母體平均數。本文首先討論一階段與二階段抽樣程序在同樣的總樣本數下，比較不同的起始樣本n0 的表現。此外在模型誤差項為不同分布時，討論兩種抽樣程序的型一誤差與檢定力表現。One of the assumptions of ...

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Multiple frame surveys in two-stage sampling
, 1984 Theory for multiple frame surveys for multistage sampling designs is complicated since various alternatives are available. Estimation of population total for such surveys is considered here for two stage sampling designs with unequal first stage units ...

A survey of potential sampling strategies for measurement of structured surfaces.
, 2009 Uniform sampling is the predominant sampling method for surface measuring instruments. However, measurement for structured surfaces brings an increasingly serious conflict between sampling range and small resolution.

Spatially correlated Poisson sampling [PDF]
, 2012 A new method for sampling from a finite population that is spread in one, two or more dimensions is presented. Weights are used to create strong negative correlations between the inclusion indicators of nearby units.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Two-stage sector sampling for estimating small woodlot attributes
, 2011 A two-stage sampling strategy is proposed to assess small woodlots outside the forests scattered on extensive territories. The first stage is performed to select a sample of small woodlots using fixed-size sampling schemes, and the second stage is ...

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The significance of Sampling Design on Inference: An Analysis of Binary Outcome Model of Children’s Schooling Using Indonesian Large Multi-stage Sampling Data [PDF]
This paper aims to exercise a rather recent trend in applied microeconometrics, namely the effect of sampling design on statistical inference, especially on binary outcome model.
