چکیده
In these supplementary materials we provide some details on the implementation of the methods developed in the paper. In addition we apply the di¤erent DID approaches using the data analyzed by Meyer, Viscusi, and Durbin (1995). These authors used DID methods to analyze the e¤ects of an increase in disability bene ts in the state of Kentucky, where the increase applied to high-earning but not low-earning workers. Next we do a small simulation study. Finally, we provide some additional proofs.

The analysis of di erences and commonalities between process models or between instances which progressed through the model (henceforth referred to as instance tra c) plays an important role in companies. For example, companies are often confronted with di erent versions or variants of a process model and hence need methods to identify redundancies or inconsistencies between them. Di erencegrap...
متن کاملSymbolic Reasoning by Diierence Reduction
We present a new approach to automated reasoning based on di erence identi cation and reduction. Di erence identi cation is based on a generalization of uni cation so that terms are made equal not only by nding substitutions for variables but also by hiding term structure. This annotation of structural di erences serves to direct rippling, a type of rewriting designed to reduce and remove di er...
متن کاملGMM-based inference in the AR(1) panel data model for parameter values where local identication fails
We are interested in making inference on the AR parameter in an AR(1) panel data model when the time-series dimension is xed and the cross-section dimension is large. We consider a GMM estimator based on the second order moments of the observed variables. It turns out that when the AR parameter equals unity and certain restrictions apply to the other parameters in the model then local identi c...

We extend previous work on di erence identi cation and reduction as a technique for automated reasoning. We generalize uni cation so that terms are made equal not only by nding substitutions for variables but also by hiding term structure. This annotation of structural di erences serves to direct rippling, a kind of rewriting designed to remove structural di erences in a controlled way. On the ...

In this study, a Multi-Objective Genetic Algorithm (MOGA) is utilized to extract interpretable and compact fuzzy rule bases for modeling nonlinear Multi-input Multi-output (MIMO) systems. In the process of non- linear system identi cation, structure selection, parameter estimation, model performance and model validation are important objectives. Furthermore, se- curing low-level and high-level ...
