The small sample size limited us in two ways: 1) It did not allow us to divide the data into separate training and test sets such assuring that the classifier can apply the rules it learned on new, unseen before, samples of the real world.
"What's path-breaking about this paper is that it both isolates, as well as one can, the effects of biological testimony on outcomes and it also does this within a sample of the real-world decision makers, the judges themselves," said Owen D.
Strength of our study are, first, that in contrast to many previous studies performed in otherwise healthy OSAS, we included patients with concomitant chronic diseases such as obesity, metabolic syndrome, hypertension, type 2 diabetes, i.e. a representative sample of the real-world OSA population.
Because the patients were recruited consecutively, the studied patient sample mirrors the real world scenario of a typical large angiology outpatient clinic.
Had your poll comprised a representative sample of economists—including economists in the real world, where most reside the results would have been quite different.Raymond PriceNew YorkGrid expectationsSIR – Your article on grid computing asks why companies would want to share computing resources in the same way as particle physicists ("One grid to rule them all", October 9th).
The study sample in RWR is much more representative of the real world situation (similar to the section of the population that receives the treatment).
The aim was to obtain a master model which measured, or stochastically-obtained, values of parameters given as input, to generate a number of samples which have the same statistical distributions of the real world ones.
And pretty soon it became clear that the producers of 'The Real World' weren't sampling the youth of America — they were unintentionally creating it".
When trying to represent the complexities of the real world, there is often not an appropriate analytic method or closed form expression for determining sample size requirements.
There are huge amounts of information in the real world.
