Two of the factors utilized are widely considered to be dummies as their value and thus their impact upon the formula typically is 0. [2] When using an O-score to evaluate the probability of company’s failure, then exp(O-score) is divided by 1 + exp(O-score). [3] The calculation for Ohlson O-score appears below: [4]
The prediction interval is conventionally written as: [, +]. For example, to calculate the 95% prediction interval for a normal distribution with a mean (μ) of 5 and a standard deviation (σ) of 1, then z is approximately 2. Therefore, the lower limit of the prediction interval is approximately 5 ‒ (2⋅1) = 3, and the upper limit is ...
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.
