After distributing test kits to 60 randomly selected households in mid-June as part of a project aiming to replace all lead water lines, Blue Island officials say the results found no immediate ...

Abstract: Finite time-vertex graph signals (FTVGS) provide an efficient representation for capturing spatio-temporal correlations across multiple data sources on irregular structures. Although ...

The NonReplacementWeightedSampler class implements a random sampler where the probability of selecting an item is proportional to its weight, and every item is sampled exactly once (without repetition ...

A weighted random item sampler (selector), where the probability of selecting an item is proportional to its weight, and every item is sampled exactly once (without repetition or replacement). The ...

The mathematician Daniel Litt has driven social media users to distraction with a series of simple-seeming but counterintuitive probability puzzles. In late January, Daniel Litt posed an innocent ...

Abstract: We consider multi-variate signals spanned by the integer shifts of a set of generating functions with distinct frequency profiles and the problem of reconstructing them from samples taken on ...

Pew Research Center designed this study to assess the current state of online survey sampling methods – both probability-based and opt-in – and determine their accuracy on general population estimates ...

When people read about a poll, they are often told something like this: Pollsters call a random group of people. Though small, we can infer this group is a representative sample of the U.S. population ...
