High nonresponse rates have become a rule in survey sampling. In panel surveys there occur additional sample losses due to panel attrition, which are thought to worsen the bias resulting from initial nonresponse. However, under certain conditions an initial wave nonresponse bias may vanish in...

In this, we argue that statistics is one of the fields of greatest significance for developing tools and techniques to find patterns in data and to give a greater understanding of them, as well as the most crucial for analyzing and calculating uncertainty. We provide a summary of several data...

Control charts are a widely used tool for statistical process control and have been continuously researched and applied for several decades. If the underlying assumptions are guaranteed, traditional charts such as the Shewhart, EWMA or CUSUM chart are a reasonable choice for monitoring...

The cumulative sum (CUSUM) control chart and the multivariate anomaly detection with the generative adversarial network (MAD-GAN) were compared for monitoring the time series data. However, it is not correct because the one-class classification was considered for the training phase and the...

This paper presents a comprehensive study of statistical and machine learning methods for predicting daily and weekly volatility of the following four cryptocurrencies: Bitcoin, Ethereum, Litecoin, and Monero. Several methods, i.e., HAR, ARFIMA, GARCH, LASSO, ridge regression, SVR, MLP, fuzzy...

In this paper, we estimate the distribution of future inflation and growth in real gross domestic product (GDP) for the Canadian economy at a daily frequency. To do this, we model the conditional moments (mean, variance, skewness and kurtosis) of inflation and GDP growth as moving averages of...

Sustainable Development Goal (SDG) 5 aims to “achieve gender equality and empower all women and girls,” and gender-specific aspects are embedded in several other SDGs. However, routine national data collection to produce gender data for SDG monitoring and other purposes is limited. Within...
