The problem of estimating the variance of the ratio estimator in sampling with probability proportional to aggregate size is investigated. The form of nonnegative unbiased variance estimators is found ...

Traders use Polymarket to predict outcomes, but the platform itself doesn't predict future events. It measures how the crowd currently estimates probability based on available information, similar to ...

This is a preview. Log in through your library . Abstract Two estimators of the probability of falling into the zero class are compared, for a family of populations related to Poisson populations. The ...

New research uncovers why an increase in probability feels riskier than a decrease. The research falls under the realm of subjective probability, also known as likelihood or risk. While past research ...

Statisticians who study coincidences are fond of saying that ordinary people don’t know how to estimate the probabilities of coincidences. To illustrate our poor statistical thinking, statisticians ...

That’s because a new framework is improving the probabilistic reasoning of LLMS like ChatGPT and Gemini. School of ...

An international team is currently closely tracking the near-Earth asteroid 2024 YR4. The impact probability estimates for the year 2032 has been reduced from a peak of 3 percent to below 0.001 ...
