A Comparison of the Missing-Indicator Method and Complete Case Analysis in Case of Categorical Data
The research aims to provide a complex analysis of the missing-indicator method’s performance in case of a categorical independent variable in regression in comparison with complete case analysis. While the latter seems to be the most popular way to handle missing data, the former appears to be a simple and effective alternative that allows making a full sample available for analysis. By means of a statistical experiment and simulated data, we examined how these methods perform in conditions that differ in a mechanism of missingness, proportion of missing data, and model specification. The final results show that, overall, both methods produce unbiased estimates of regression coefficients, but crucially biased estimates of their standard errors and additional statistics such as R2, adjusted R2, and F-statistic, especially in case of a missing-indicator method. We explain these results by contribution of a missing-indicator variable, coefficient of which always turns out to be significant and far away from zero.

This article explores the factors driving the regional differentiation of judicial activity in the post-reform Russian Empire. The historiography is currently divided between two poles: the paradigm of legal dualism, which postulates the alienation of rural and non-Russian (inorodtsy) populations from the Crown courts, and the opposing thesis of mass grassroots legalism, large- ly verified ...

“Leaderlessness” is widely held to be a defining feature of contemporary mass mobilization, yet the claim rests on a handful of recent cases. We offer the first systematic cross-national analysis of this phenomenon from 1791 to 2019. We show that the absence of leadership is real but older and more modest than claimed: the share ...

Elaborating on Welzel et al.'s "Cool Water Theory," our study zooms into the more limited (albeit still varied) framework conditions of Russia's huge territory. Within Russia's confines, we examine how the combination of moderately cool seasons with steady rain (i.e., Cool Water) affects sub-national areas' contemporary societal progress in two modernization indicators: material prosperity in ...

This work is devoted to a theoretical explanation of the Easterlin paradox, according to which long-term economic growth does not make average level of people's happiness increasing. By happiness, we mean the intensity of emotions people experience while comparing their new income with its expected value, or the target income with its original value. In the first case, ...

This article is devoted to the phenomenon of intrinsic motivation, to understand which two models are proposed. We study how positive/negative intrinsic motivation to work (experienced utility) affects worker's individual labour supply (model I) and the amount of effort they exert (model II). In model I, we use intrinsic motivation to explain the positive/negative slope ...

We argue that a classification-based approach to measuring cultural differences across countries or subnational regions is a promising complement, and sometimes an alternative, to the widely used dimensional method in cross-cultural research. The latter summarises cultural variation using continuous dimensions, for example, Hofstede’s famous individualism-collectivism dimension. However, this approach relies on strong parametric assumptions, which are ...

Non-probability web surveys offer several advantages over face-to-face (F2F) interviews—they are cheaper, faster, more accessible, and reduce interviewer effects and desirability bias. As such, they are increasingly popular in both academic and commercial research. However, they often yield demographically biased samples, raising concerns about the accuracy of the resulting public opinion estimates. Most studies on ...

Research of the impact of kin alloparenting on reproduction mainly focuses on mother’s parents and parents-in-law. The impact on fertility of extended families and the alloparental help with childcare they can provide has received much less attention. Moreover, there is an important lacuna in the existing studies of this problem, as it is mostly approached ...

Для понимания какого-либо качества, как правило, выбирается, некоторая подходящая для его оценки шкала (скажем, от 1 до 5), и, согласно этой шкале, качеству присваиваются одна или несколько оценок. Эти оценки затем преобразуются в одну, “усредненную”, оценку; например, выбирается среднее арифметическое. Так, несданная сессия с тремя баллами 5, 2 и 5 “характеризуется’’ средней оценкой хорошо: (5+2+5)/3 = ...

The notion of “political accommodation” applied to the theory and practice of managing cultural diversity could enrich the Russian academic dictionary. Liberal democratic states invented specific mechanisms for political accommodation of cultural differences.
