• Abstract summary: We reanalyze the only known controlled experiment investigating the impact of passive voice on the subsequent activity of domain modeling. Our results reveal that the effects observed by the original authors turned out to be much less significant than previously assumed.

• Abstract: The quality of requirements specifications may impact subsequent, dependent software engineering (SE) activities. However, empirical evidence of this impact remains scarce and too often superficial as studies abstract from the phenomena under investigation too much. Two of these abstractions are caused by the lack of frameworks for causal inference and frequentist methods which reduce complex data to binary results. In this study, we aim to demonstrate (1) the use of a causal framework and (2) contrast frequentist methods with more sophisticated Bayesian statistics for causal inference. To this end, we reanalyze the only known controlled experiment investigating the impact of passive voice on the subsequent activity of domain modeling. We follow a framework for statistical causal inference and employ Bayesian data analysis methods to re-investigate the hypotheses of the original study. Our results reveal that the effects observed by the original authors turned out to be much less significant than previously assumed. This study supports the recent call to action in SE research to adopt Bayesian data analysis, including causal frameworks and Bayesian statistics, for more sophisticated causal inference.

  This paper proposes techniques to enhance the performance of non-causal models for causal inference using data from randomized experiments. In domains like advertising, customer retention, and precision medicine, non-causal models that predict outcomes under no intervention are often used to score individuals and rank them according to the expected effectiveness of an intervention.

  This work investigates the impact of different noise levels on the ability of Additive Noise Models to identify the direction of the causal relationship. We use an exhaustive range of models where the level of additive noise gradually changes from 1% to 10000% of the causes' noise level. The results of the experiments show that ANMs methods can fail to capture the true causal direction for some levels of noise.
