mistake that the probabilities for any binary trial are 0.5. Would anyone expect that in a random sample of two individuals from California that one would be infected with HIV and the other would not? Or expect that the sun would rise one day and not the next? In addition, uniform priors on the real line, or even normal distributions with mean zero and huge variances, say very silly things, for...

In this paper, we investigate property testing whether or not a degree d multivariate polynomial is a sum of squares or is far from a sum of squares. We show that if we require that the property tester always accepts YES instances and uses random samples, nΩ(d) samples are required, which is not much fewer than it would take to completely determine the polynomial. To prove this lower bound, we ...

traditional survey methods may cause refusals to respond or untruthful replies when encounter the sensitive questions. the randomized response technique (rrt) is designed to decrease social desirability bias and obtain reliable estimates. this study aimed to apply these new methods on the sensitive questions survey.simmons model was applied in the survey of issues relevant to commercial sex amo...

We propose a new approach to the estimation of join selectivity. The technique, which we have called “systematic sampling”, is a novel variant of the sampling-based approach. Systematic sampling works as follows: Given a relation R of N tuples, with a join attribute that can be accessed in ascending/descending order via an index, if n is the number of tuples to be sampled from R, select a tuple...

Fig. 2: Results of downsampling experiments of the brain for subsampling with R=10 and R=18. IRGN reconstructions of conventional regular Cartesian subsampling with autocalibration lines at the center of k-space (first column), radial subsampling (second column), variable density ran...

Random sampling strategies play critical roles in ran-domized motion planners, which are promising and practical for motion planning problems with many degrees of freedom (dofs). In this paper, we explore random sampling in a constrained connguration space { the contact connguration space between two polyhedra, motivated by the need for generating contact motion plans. Given a contact formation...
