Intraclass correlation coefficient(ICC)是一种用于衡量同一样本内变量之间相互依赖程度的统计指标,它是一种用来估计可靠性和一致性的方法。ICC是一种更加强大和多维度的统计方法,可以用来评估不同观察者对同一样本的观测结果之间的一致性和相关性。ICC可以用来评估不同观察者、不同方法或不同时间对同一样本所得结果的一...
Intraclass correlation coefficientRelative consistencyIntraclass correlation coefficients are estimated using appropriate analysis of variance models that are commonly used in behavioral measurement, biometric, and psychometric. The ICCs estimation accuracy is quantified by the degree of their sampling variability ...

intraclass correlation modelconfidence regionasymptotic expansiontwo-stage proceduresequential procedureThe problem of constructing fixed-size confidence regions for estimating the mean vector of a multivariate normal distribution is considered when the covariance matrix has the intraclass correlation coefficient. ...
a period of time. My model has a random intercept and a random coefficient (time) at both patient and artery levels. Time is my only fixed effect. My goal is to determine the intra-class correlation coefficient (ICC) for the change over time at the patient level. In other words, to ...
The influences of window size of polynomial derivation and smoothing and wavelength selected by correlation coefficient on the correction model were discussed. 采用多通道PDA型近红外光谱仪,应用偏最小二乘法建立了菜籽油中芥酸含量与近红外透射光谱的校正模型,讨论多项式求导及平滑的窗口宽度和相关系数法筛选有效...
intra-class correlation modelcost of not knowing the varianceIn the intraclass correlation model when the variance σ2 and the intraclass correlation coefficient 'p are both unknown, Tukey's confidence intervals for the contrasts in the means are obtained for the fixed sample and the sequential ...

This article revisits the multivariate normal model with permutation-symmetric covariance matrix. Our focus is on the common correlation coefficient . It is shown that the MLE of does belong to the allowable interval no matter what kind of information about the population parameters is available. ...
