Partition Testing Does Not Inspire Confidence

Exact hypothesis testing and confidence interval for mean of the exponential distribution under Type-I progressive hybrid censoring

 ‎Censored samples are discussed in experiments of life-testing; i.e‎. ‎whenever the experimenter does not observe the failure times of all units placed on a life test‎. ‎In recent years‎, ‎inference based on censored sampling is considered‎, ‎so that about the parameters of various distributions such as ‎normal‎, ‎exponential‎, ‎gamma‎, ‎Rayleigh‎, ‎Weibull‎, ‎log normal‎, ‎inverse Gaussian‎, ...

Evaluating the Contributions of Individual Variables to a Quadratic Form

Quadratic forms capture multivariate information in a single number, making them useful, for example, in hypothesis testing. When a quadratic form is large and hence interesting, it might be informative to partition the quadratic form into contributions of individual variables. In this paper it is argued that meaningful partitions can be formed, though the precise partition that is determined w...

On some reliability estimation problems in random and partition testing

Studies have shown that random testing can be an effective testing strategy. One of tbe goals of testing is to estimate the reliability of tbe program from tbe test outcomes. In tbis paper we extend tbe Tbayer-Lipow-Nelson reliability model to account for tbe cost of errors. Also we compare random with partition testing by looking at upper confidence bounds for the cost weighted performance of ...

Detecting divergent robot behavior with multi-rigid body simulation and random sampling

The motion of robots and objects in our world is often highly dependent upon contact. When contact is expected but does not occur or when contact is not expected but does occur, robot behavior diverges from plan, often disastrously. We describe an approach that uses multi-rigid body simulation with contact toward predicting likely such behavioral divergences on real robots. Our approach, and ot...

Does the potential overuse of routine post PCI stress testing and revascularization inspire courage to embrace more evidence-based decision making?
