Application of Equal Local Levels to Improve Q-Q Plot Testing Bands with R Package qqconf

  title={Application of Equal Local Levels to Improve Q-Q Plot Testing Bands with R Package qqconf},
  author={Eric Weine and Mary Sara McPeek and Mark Abney},
Quantile-Quantile (Q-Q) plots are often difficult to interpret because it is unclear how large the deviation from the theoretical distribution must be to indicate a lack of fit. Most Q-Q plots could benefit from the addition of meaningful global testing bands, but the use of such bands unfortunately remains rare because of the drawbacks of current approaches and packages. These drawbacks include incorrect global Type I error rate, lack of power to detect deviations in the tails of the distribution…

Asymptotics of goodness-of-fit tests based on minimum p-value statistics

ABSTRACT This paper provides some new results on the asymptotics of goodness-of-fit (GOF) tests based on minimum p-value statistics. In connection with detectability of sparse signals in

The Power to See: A New Graphical Test of Normality

A simple new graphical procedure is discussed which provides simultaneous confidence bands for a normal quantile–quantile plot which define a test of normality and are narrower in the tails than those related to the Kolmogorov–Smirnov test.

For example, the subjects in a prospective clinical trial or Randomized Controlled Trial (RCT) might initially be classified into treated and untreated (more often called “control”) groups, then later beclassified into successes and failures, which would be tantamount to the hypothesis that the treated and control groups do not differ in their success rates.

Alternatives to the Median Absolute Deviation

Abstract In robust estimation one frequently needs an initial or auxiliary estimate of scale. For this one usually takes the median absolute deviation MAD n = 1.4826 med, {|xi − med j x j |}, because

Fast calculation of p-values for one-sided Kolmogorov-Smirnov type statistics.

We present a method for computing exact p-values for a large family of one-sided continuous goodness-of-fit statistics. This includes the higher criticism statistic, one-sided weighted

Confidence Bands for Quantile Functions: A Parametric and Graphic Alternative for Testing Goodness of Fit

Abstract This article derives simultaneous 100(1 − α)% confidence intervals for the quantiles of a normal distribution using a method first proposed by Cheng and Iles and independently rediscovered
