I've become alarmed recently at the number of young engineers (i.e. those with less than 5 years of work experience), who seem to have missed the college course on applied probability and don't know ...

Sample size and power calculations are available for one-sample and two-sample paired and independent designs, when the proposed analysis is construction of confidence intervals of a mean (one-sample) ...

For survival probabilities with censored data, Rothman (1978, Journal of Chronic Diseases 31, 557-560) has recommended the use of quadratic confidence limits based on the assumption that the product ...

An expected volume coefficient (EV) is defined and proposed to displace volume and selectivity as criteria for the evaluation of confidence sets, and a proposal for evaluation is given. This proposal ...

Confidence intervals show the likelihood a data range contains the true mean, aiding investment decisions. A wider interval suggests lower estimate accuracy, influencing market and risk analysis ...

The probability that the null hypothesis will be rejected when it is actually true is called the false positive rate and is determined by the significance level of the test (called alpha which is ...
