We propose a multivariate regime switching model based on a Student- copula function with parameters controlling the strength of correlation between variables and that are governed by a latent Markov process. To estimate model parameters by maximum likelihood, we consider a two-step procedure carried out through the Expectation–Maximisation algorithm. To address the main computational burden related to the estimation of the matrix of dependence parameters and the number of degrees of freedom of the Student- copula, we show a novel use of the Lagrange multipliers, which simplifies the estimation process. The simulation study shows that the estimators have good finite sample properties and the estimation procedure is computationally efficient. An application concerning log-returns of five cryptocurrencies shows that the model permits identifying bull and bear market periods based on the intensity of the correlations between crypto assets.
我们提出了一种基于 Student- t copula 函数的多变量制度转换模型，其参数控制着变量之间的相关性强度，并受潜在马尔可夫过程的支配。为了用最大似然法估计模型参数，我们考虑通过期望最大化算法分两步进行。为了解决与估计依赖性参数矩阵和 Student- t 协程自由度数相关的主要计算负担，我们展示了拉格朗日乘数的一种新用法，它简化了估计过程。模拟研究表明，估计器具有良好的有限样本特性，估计过程的计算效率也很高。有关五种加密货币对数收益率的应用表明，该模型可以根据加密资产之间的相关性强度来识别牛市和熊市时期。

In this paper, we develop a fully parametric quantile regression model based on the generalised three-parameter beta (GB3) distribution. Beta regression models are primarily used to model rates and proportions. However, these models are usually specified in terms of a conditional mean. Therefore, they may be inadequate if the observed response variable follows an asymmetrical distribution. In addition, beta regression models do not consider the effect of the covariates across the spectrum of the dependent variable, which is possible through the conditional quantile approach. In order to introduce the proposed GB3 regression model, we first reparameterise the GB3 distribution by inserting a quantile parameter, and then we develop the new proposed quantile model. We also propose a simple interpretation of the predictor–response relationship in terms of percentage increases/decreases of the quantile. A Monte Carlo study is carried out for evaluating the performance of the maximum likelihood estimates and the choice of the link functions. Finally, a real COVID-19 dataset from Chile is analysed and discussed to illustrate the proposed approach.

In this paper, we survey the recent development of inversion-free Newton's method, which directly avoids computing the inversion of Hessian, and demonstrate its applications in estimating parameters of models such as linear and logistic regression. A detailed review of existing methodology is provided, along with comparisons of various competing algorithms. We provide numerical examples that highlight some deficiencies of existing approaches, and demonstrate how the inversion-free methods can improve performance. Motivated by recent works in literature, we provide a unified subsampling framework that can be combined with the inversion-free Newton's method to estimate model parameters including those of linear and logistic regression. Numerical examples are provided for illustration.

Auxiliary variables with known population totals are extensively used in survey sampling to construct generalised regression (GR) estimators or optimal regression (OR) estimators of totals or means of study variables. This article explores the possibility of improving the efficiency of such estimators when continuous auxiliary variables are used in the regression estimation jointly with appropriate power functions of them, provided that the values of the auxiliary variables are known for all units in the population. The efficiency gain is determined analytically in the case of the OR estimator. A practical criterion for choosing the power functions that maximise the efficiency gain, involving the coefficient of determination in the regression fit of the study variable, is proposed for both the OR estimation and the more practicable, but generally less efficient, GR estimation. Furthermore, the effect of adding a power function of a continuous auxiliary variable in regression estimation is investigated when this variable is also used at the design stage. A simulation study shows that the joint use of a continuous auxiliary variable and a power function of it chosen according to the proposed criterion may improve considerably the efficiency of OR estimation, and much more the efficiency of GR estimation.
在调查抽样中，已知总体的辅助变量被广泛用于构建研究变量总体或均值的广义回归（GR）估计值或最优回归（OR）估计值。本文探讨了当连续辅助变量与适当的幂函数一起用于回归估计时，如果辅助变量的值是已知的，则可以提高此类估计器的效率。在 OR 估计器的情况下，效率增益是通过分析确定的。针对 OR 估计和更实用但通常效率较低的 GR 估计，提出了一个实用标准，用于选择能使效率增益最大化的幂函数，该标准涉及研究变量回归拟合的决定系数。此外，还研究了在回归估计中添加连续辅助变量的幂函数的效果，当该变量也在设计阶段使用时。模拟研究表明，联合使用连续辅助变量和根据所提标准选择的幂函数，可以显著提高 OR 估计的效率，并大大提高 GR 估计的效率。

Summary In this paper, we introduce two new randomised response models for estimating the prevalence of two sensitive characteristics and their overlap in a population by making use of a single deck of cards. The proposed models ensure the privacy of the respondents and also reduce the burden on the respondents as they require the random selection of only one card from a deck of cards each of which contains a pair of questions that are to be answered in order. The variance expressions of the proposed estimators are derived and matched to their Cramer–Rao lower bounds of variances. A simulation study has been carried out to compare the proposed models to each other for least protection. Lastly, a real survey application, related to the acceptability of the vaccines produced by Pfizer and Moderna is included. We had findings in Summer 2021 similar to those of the Harvard Study done in December 2021, which was based on a half‐million data values, that shows the cost effectiveness of the survey design.

Summary Accurate estimates of subnational health and demographic indicators are critical for informing policy. Many countries collect relevant data using complex household surveys, but when data are limited, direct weighted estimates of small area proportions may be unreliable. Area level models treating these direct estimates as response data can improve precision but often require known sampling variances of the direct estimators for all areas. In practice, the sampling variances are estimated, so standard approaches do not account for a key source of uncertainty. To account for variability in the estimated sampling variances, we propose a hierarchical Bayesian spatial area level model for small area proportions that smooths both the estimated proportions and sampling variances to produce point and interval estimates of rates of interest. We demonstrate the performance of our approach via simulation and application to vaccination coverage and HIV prevalence data from the Demographic and Health Surveys.
