The Marshall-Edgeworth index, credited to Marshall (1887) and Edgeworth (1925), [11] is a weighted relative of current period to base period sets of prices. This index uses the arithmetic average of the current and based period quantities for weighting. It is considered a pseudo-superlative formula and is symmetric. [12]
The ADX combines them and smooths the result with a smoothed moving average. To calculate +DI and -DI, one needs price data consisting of high, low, and closing prices each period (typically each day). One first calculates the directional movement (+DM and -DM): UpMove = today's high − yesterday's high DownMove = yesterday's low − today's low
[1] The U* index theory has been validated through two different physical experiments. [3] Since the U* index predicts the load paths based on the structural stiffness, it is not affected by the stress concentration problems. The load transfer analysis using the U* index is a new design paradigm for vehicle structural design.
Numerous historical reviews of the moving load problem exist. [1] [2] Several publications deal with similar problems. [3] The fundamental monograph is devoted to massless loads. [4] Inertial load in numerical models is described in [5]
To calculate the relative strength of a particular stock, divide the percentage change over some time period by the percentage change of a particular index over the same time period. [ 2 ] Relative Rotation Graph

The American Public Works Association publication, Special Report #62, describes the use and value of facility condition rating systems in Chapter 3.6. Within the US Federal Government, the "condition index" (CI) is a general measure of the constructed asset's condition at a specific point in time. [2]
The volume or weight loss is initially curvilinear. The wear rate per unit sliding distance in the transient wear regime decreases until it has reached a constant value in the steady-state wear regime. Hence the standard wear coefficient value obtained from a volume loss versus distance curve is a function of the sliding distance. [3]
