Margaret McCartney: The zombie statistic behind the push for seven day working.
Apparently, if you are admitted to hospital at the weekend you are 16%more likely to die. This was featured on Radio 4’sNews Quiz, indicating that it’s passed into the realm of the “zombie statistic”—namely, completely spurious but widely accepted as fact. It started with a 2012 paper in the Journal of the Royal Society of Medicine. The BBC then reported that patients were “‘more likely to die’...
متن کاملInterrater reliability: the kappa statistic
The kappa statistic is frequently used to test interrater reliability. The importance of rater reliability lies in the fact that it represents the extent to which the data collected in the study are correct representations of the variables measured. Measurement of the extent to which data collectors (raters) assign the same score to the same variable is called interrater reliability. While ther...
متن کاملan investigation of the spatial changes of one-day (24-hour) precipitation in the supply of iran precipitation days and amount
in different regions, precipitation takes place with different persistencies and every persistency supplies a share of rainfall days and precipitation. therefore, the importance of rainfall persistence could be evaluated in all places. iran is located in mid-latitude of an arid region, in which the mean rainfall is 250 mm and it has dramatic tempo-spatial changes. rainfalls with short persisten...
متن کاملEstimation Sampling Sampling Estimation Sampling Test Statistic Test Statistic
In this paper, we introduce a Goodness-of-Fit test for the Multivariate Exponential Power (MEP) distribution, a multivariate extension of the Generalized Gaussian, which has recently gained considerable interest as a model for wavelet coefficients in the context of color image retrieval and spread-spectrum watermarking. We present a size and power study of this test and show Goodness-of-Fit res...
متن کاملPearson’s Goodness of Fit Statistic as a Score Test Statistic∗
For any generalized linear model, the Pearson goodness of fit statistic is the score test statistic for testing the current model against the saturated model. The relationship between the Pearson statistic and the residual deviance is therefore the relationship between the score test and the likelihood ratio test statistics, and this clarifies the role of the Pearson statistic in generalized li...
