Placing Confidence Limits on Polarization Measurements
The determination of the true source polarization given a set of measurements is complicated by the requirement that the polarization always be positive. This positive bias also hinders construction of upper limits, uncertainties, and confidence regions, especially at low signal-to-noise levels. We generate the likelihood function for linear polarization measurements and use it to create confid...
متن کاملPlacing confidence limits on the molecular age of the human-chimpanzee divergence.
Molecular clocks have been used to date the divergence of humans and chimpanzees for nearly four decades. Nonetheless, this date and its confidence interval remain to be firmly established. In an effort to generate a genomic view of the human-chimpanzee divergence, we have analyzed 167 nuclear protein-coding genes and built a reliable confidence interval around the calculated time by applying a...
متن کاملThe fallacy of placing confidence in confidence intervals
Interval estimates - estimates of parameters that include an allowance for sampling uncertainty - have long been touted as a key component of statistical analyses. There are several kinds of interval estimates, but the most popular are confidence intervals (CIs): intervals that contain the true parameter value in some known proportion of repeated samples, on average. The width of confidence int...
متن کاملGamma-Ray Burst Polarization: Limits from RHESSI Measurements
Using the RHESSI satellite as a Compton polarimeter, a recent study claimed that the prompt emission of GRB021206 was almost fully linearly polarized. This was challenged by a subsequent reanalysis. We present an novel approach, applying our method to the same data. We identify Compton scattering candidates by carefully filtering events in energy, time, and scattering geometry. Our polarization...
متن کاملComments on Methods for Setting Confidence Limits
I discuss a number of issues which arise when computing confidence limits by frequentist or Bayesian methods. I begin with a reminder why P(hypothesis data) cannot be determined if the only input is the ‘objective’ data. I then discuss confidence intervals, with emphasis on the ‘unified approach’ based on likelihood-ratio ordering, and related methods. A number of issues arise, including condit...
