Definitions of direct and indirect effects are given for settings^{ }in which individuals are clustered in groups or neighborhoods^{ }and in which treatments are administered at the group level.^{ }A particular intervention may Read the rest of this entry »

Sequence analysis was originally invented by biologists with the aim of comparing DNA sequences in order to find out to what extent two DNA strands are homologous Read the rest of this entry »

The optimal matching (OM) algorithm is widely used for sequence analysis insociology. It has a natural interpretation for discrete-time sequences but isalso widely used for life-history data, which are Read the rest of this entry »

This article addresses the question of the effects of cost setting on the kind of temporal patterns optimal matching (OM) can uncover when applied to social science data. Read the rest of this entry »

Categorical time series, covering comparable time spans, are often quite different in a number of aspects: the number of distinct states, the number of transitions, and the distribution of durations Read the rest of this entry »

Liu (2007) analyzes an interesting individual election contest in which the racial identities of voters and registrants are known. He uses this information to calculate true turnout rates by race Read the rest of this entry »

Ordinal-level measures are very common in social science research.^{ }Researchers often analyze ordinal dependent variables using^{ }the proportional odds logistic regression model. However, Read the rest of this entry »

This article is an empirical evaluation of the choice of fixed^{ }cutoff points in assessing the root mean square error of approximation^{ }(RMSEA) test statistic as a measure of goodness-of-fit in StructuralEquation Models. Using simulation data, Read the rest of this entry »

This article offers a new approach to the identification of^{ }age–period–cohort (APC) models that builds on Pearl’s^{ }work on nonparametric causal models, in particular his front-door^{ }criterion for the identification of causal effects. Read the rest of this entry »

The credibility of quantitative social science benefits from^{ }policies that increase confidence that results reported by one^{ }researcher can be verified by others. Concerns about replicability^{ }have increased Read the rest of this entry »

This article develops a unified framework, based on Rossi’s^{ }factorial survey method, for studying positive beliefs and normative^{ }judgments. The framework enables estimation Read the rest of this entry »

The model selection literature has been generally poor at reflecting^{ }the deep foundations of the Akaike information criterion (AIC)^{ }and at making appropriate comparisons to the Bayesian information^{ }criterion (BIC). There is a clear philosophy Read the rest of this entry »
