The ulcer index is a stock market risk measure or technical analysis indicator devised by Peter Martin in 1987, [1] and published by him and Byron McCann in their 1989 book The Investors Guide to Fidelity Funds. It is a measure of downwards volatility, the amount of drawdown or retracement over a period. [2]
A complexometric indicator is an ionochromic dye that undergoes a definite color change in presence of specific metal ions. [1] It forms a weak complex with the ions present in the solution, which has a significantly different color from the form existing outside the complex. Complexometric indicators are also known as pM indicators. [2]
Such indicators have some special properties. For example, the following statements are all true for an indicator function that is trigonometrically convex at least on an interval (,): [1]: 55–57 [2]: 54–61
This is the aim of multiple factor analysis which balances the different issues (i.e. the different groups of variables) within a global analysis and provides, beyond the classical results of factorial analysis (mainly graphics of individuals and of categories), several results (indicators and graphics) specific of the group structure.
Much of indicator analysis is looking for the specific indicators that will signal a coming upheaval, but tracking how factors change over time can result in very useful trend analysis as well that is still considered a part of indicator analysis as a practice. An example of indicator analysis for stability in Albania, with three categories of ...
A data set would contain one such triple for each rock in a sample of rocks. In high throughput sequencing, data obtained are typically transformed to relative abundances, rendering them compositional. In probability and statistics, a partition of the sampling space into disjoint events is described by the probabilities assigned to such events.
In finance, MIDAS (an acronym for Market Interpretation/Data Analysis System) is an approach to technical analysis initiated in 1995 by the physicist and technical analyst Paul Levine, PhD, [1] and subsequently developed by Andrew Coles, PhD, and David Hawkins in a series of articles [2] and the book MIDAS Technical Analysis: A VWAP Approach to Trading and Investing in Today's Markets.

Note that the distribution's mode will lie with p N-2 's weight, i.e. in the graph above p 8 carries the highest weighting. An N of 1 is invalid. The easiest way to calculate the triple EMA based on successive values is just to apply the EMA three times, creating single-, then double-, then triple-smoothed series. The triple EMA can also be expressed directly in terms of the prices as below ...
