Estimating Dynamics of National Power: a Bayesian Principal Components Approach
P. 1–4.
We offer a novel approach to the measurement of national power. The approach consists of two related parts: raw data processing and a measurement model. Suggested approach improves existing practices by allowing dynamic changes in the weights of national power components. It also returns credible intervals around point estimates, paving the way for statistical comparisons of national power values across time and space.

Legacy soil maps remain essential for national land-use planning. However, their thematic accuracy and spatial resolution are often insufficient for contemporary applications requiring reliable estimates. This study presents a digital soil-mapping approach to update legacy soil information without extensive field sampling, demonstrated for arable lands in the Republic of Tatarstan (4.5 million ha). The proposed ...

This article proposes an approach to forecasting fertility using Google Trends search query statistics. Unlike existing studies on fertility forecasting, this paper introduces a method for aggregating thematic search queries using machine learning techniques, reducing the dimensionality of search queries through principal component analysis, and incorporating a lag structure of search queries ranging from 1 ...

The article is devoted to clarifying the heuristic possibilities of the case-based approach (case study) in comparative political science. This approach correlates with ideographic knowledge within the framework of the division of epistemology into nomothetic (comprehension of patterns) and ideographic (descriptive) sciences (W. Windelband); with understanding knowledge within the framework of the distinction between explanatory ...

Empirical research in Comparative Politics and International Relations is often built not only on statistical data, but also on expert evaluation data. However, the methods of data analysis employed in this case often fail to account for the differences between statistical and expert evaluation data, and disregard the extra uncertainty in the latter. This article ...

The paper analyses the influence of institutional development level on bilateral foreign direct investment (FDI) flows. The theory suggests that more developed institutions in both home and host countries should increase FDI flows between countries. At the same time existing empirical research often have controversial results. We use the database on bilateral FDI flows for ...

It is a common practice among social scientists to use “factor analysis” and “principal components analysis” interchangeably, even though PCA is not a factor extraction method, but a dimension reduction technique. Most of the recent studies with factor analysis rely solely on PCA or fail to specify which factor extraction method was used. Supposedly, it ...

Accountability—constraints on a government’s use of political power—is one of the cornerstones of good governance. However, conceptual stretching and a lack of reliable measures have limited cross-national research on this concept. To address this research gap, we use V-Dem data and innovative Bayesian methods to develop new indices of accountability and its subtypes: the extent ...
