This included going with modular structure, a "ball swarm" design for the chart depicting each candidate's chances, and the addition of a "forecast mascot" named Fivey Fox. [538 72] An episode of "Chart Chat" discussing the design described the direction saying "FiveThirtyEight has leaned heavily towards a cutesy and engaging approach. The ...
This little-known but serious issue can be overcome by using an accuracy measure based on the logarithm of the accuracy ratio (the ratio of the predicted to actual value), given by (). This approach leads to superior statistical properties and also leads to predictions which can be interpreted in terms of the geometric mean.
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
Their final prediction on November 8, 2016, gave Clinton a 71% chance to win the 2016 United States presidential election, [89] while other major forecasters had predicted Clinton to win with at least an 85% to 99% probability.
Prediction intervals are commonly used as definitions of reference ranges, such as reference ranges for blood tests to give an idea of whether a blood test is normal or not. For this purpose, the most commonly used prediction interval is the 95% prediction interval, and a reference range based on it can be called a standard reference range.
Ignoring national trends, Clinton has a 99.9% chance of winning here. Two electoral votes in this state are allocated at the district level. We use Cook Political Report ratings for those: solidly Democrat and leaning Republican .
Confidence bands can be constructed around estimates of the empirical distribution function.Simple theory allows the construction of point-wise confidence intervals, but it is also possible to construct a simultaneous confidence band for the cumulative distribution function as a whole by inverting the Kolmogorov-Smirnov test, or by using non-parametric likelihood methods.
