A martingale is a mathematical series in which the best prediction for the next number is the current number. The concept is used in probability theory, to estimate the results of random motion. For example, suppose that you have $50 and bet it all on a coin toss. How much money will ...
Notes: Graphs for non-parametric preference measures represent proportion of each outcome at levels of the preference measure. Whiskers represent 95 % confidence intervals. Outcomes are a binary measure of Herpes Simplex Virus Type-2 (HSV-2) positive status and a count of number of sexual partners...
statistic (or area under a receiver operating characteristic curve) is often used to assess the discriminatory power of a prediction model.28–31 Discriminatory power measures the ability of a model to distinguish between those individuals having a partic- ular outcome and others without the outcome...
, 31. Discriminatory power measures the ability of a model to distinguish between those individuals having a particular outcome and others without the outcome. It corresponds to the probability that a randomly selected individual who develops the disease has a higher predicted risk than that of a ...
In this season of global soccer competitions and hotly contested political primaries, bookies and pundits are scouring every evolving scrap of information and sifting through mountains of data in an effort to predict the outcome of the next game or elect
The division or branching process was accomplished by searching all input variables (ie, potential predictors) and all values of each input variable to find the individual variable and its cut-off value that best classified patients as responders or non-responders, as determined by some statistical...
Limitations: The complication rate relies on physician self-reporting. Conclusions: Rectal retroflexion during colonoscopy is associated with a low rate of perforation, yet this serious complication can occur even in the hands of experienced endoscopists. Most cases of rectal perforation during retro...
