Matching Procedures in Field Experiments

چکیده
To achieve the perfect experimental comparison, the field experimentalist would like to replay history. In this fantasy, a new approach or a new program would be tried. Then, the history rewind button would be pressed to replay events under the traditional or existing program with the same human beings to see whether things turned out differently. No one could argue that the two groups were dissimilar because they were the same people.

Adaptive Approximate Record Matching
Typographical data entry errors and incomplete documents, produce imperfect records in real world databases. These errors generate distinct records which belong to the same entity. The aim of Approximate Record Matching is to find multiple records which belong to an entity. In this paper, an algorithm for Approximate Record Matching is proposed that can be adapted automatically with input error...
متن کاملA Novel Assisted History Matching Workflow and its Application in a Full Field Reservoir Simulation Model
The significant increase in using reservoir simulation models poses significant challenges in the design and calibration of models. Moreover, conventional model calibration, history matching, is usually performed using a trial and error process of adjusting model parameters until a satisfactory match is obtained. In addition, history matching is an inverse problem, and hence it may have non-uni...
متن کاملPretreatment quality control of single isocenter half- beam treatment planning technique using an amorphous silicon electronic portal-imaging device (EPID)
Introduction: Electronic portal imaging devices (EPIDs) are fundamentally used for instantaneous verification of the patient set‐up, block shape, and leaf positions during radiation therapy. In radiotherapy, situations arise in which an inclined PTV must be treated mutually with adjacent nodal regions. This methodology is most widely used for matching tangential/lateral breas...
متن کاملMatching and challenge gifts to charity: evidence from laboratory and natural field experiments
Matching and Challenge Gifts to Charity: Evidence from Laboratory and Natural Field Experiments This study designs a natural field experiment linked to a controlled laboratory experiment to examine the effectiveness of matching gifts and challenge gifts, two popular strategies used to secure a portion of the $200 billion annually given to charities. We find evidence that challenge gifts positiv...
متن کاملFractured Reservoirs History Matching based on Proxy Model and Intelligent Optimization Algorithms
In this paper, a new robust approach based on Least Square Support Vector Machine (LSSVM) as a proxy model is used for an automatic fractured reservoir history matching. The proxy model is made to model the history match objective function (mismatch values) based on the history data of the field. This model is then used to minimize the objective function through Particle Swarm Optimization (...
