  2. Approximations of π - Wikipedia

    en.wikipedia.org/wiki/Approximations_of_π

    Pi Hex was a project to compute three specific binary digits of π using a distributed network of several hundred computers. In 2000, after two years, the project finished computing the five trillionth (5*10 12), the forty trillionth, and the quadrillionth (10 15) bits. All three of them turned out to be 0.

  3. Stock market prediction - Wikipedia

    en.wikipedia.org/wiki/Stock_market_prediction

    Intrinsic value (true value) is the perceived or calculated value of a company, including tangible and intangible factors, using fundamental analysis. It's also frequently called fundamental value. It is used for comparison with the company's market value and finding out whether the company is undervalued on the stock market or not.

  4. Prediction interval - Wikipedia

    en.wikipedia.org/wiki/Prediction_interval

    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 ...

  5. Value network analysis - Wikipedia

    en.wikipedia.org/wiki/Value_network_analysis

    Value network analysis (VNA) is a methodology for understanding, using, visualizing, optimizing internal and external value networks and complex economic ecosystems. [ 1 ] [ 2 ] The methods include visualizing sets of relationships from a dynamic whole systems perspective.

  6. Time-weighted average price - Wikipedia

    en.wikipedia.org/wiki/Time-weighted_average_price

    A TWAP strategy is often used to minimize a large order's impact on the market and result in price improvement. [2] High-volume traders use TWAP to execute their orders over a specific time, so they trade to keep the price close to that which reflects the true market price. TWAP orders are a strategy of executing trades evenly over a specified ...

  7. Coverage probability - Wikipedia

    en.wikipedia.org/wiki/Coverage_probability

    In statistical prediction, the coverage probability is the probability that a prediction interval will include an out-of-sample value of the random variable. The coverage probability can be defined as the proportion of instances where the interval surrounds an out-of-sample value as assessed by long-run frequency. [2]

    The Life2vec model made predictions with 78% accuracy. Characteristics like higher income and holding a leadership role lead to longer lifespans, while habits like smoking can shorten it.

  9. Confidence and prediction bands - Wikipedia

    en.wikipedia.org/wiki/Confidence_and_prediction...

    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.
