Dispersion

In statistics, the placement of data points along a chart relative to an average or mean line. Dispersion is important to finance as the data points of say, a stock, determine the mean, which in turn helps determines the stock's trend. Dispersion is also used to determine volatility: data points all over the chart indicate that a stock has wild fluctuation in price.

The sea clutter data (Figure 9(a)) and corresponding data of a refractivity profile (Figure 9(b)) measured in Huanghai, China, August 1, 2014 are considered here.
The refractivity profiles were obtained by an instrumented helicopter and the data include 32 profiles in the horizontal range of 60 km.
The first formula defines the linear relationship between osmolality, [phi], and refractivity as measured on a reference scale:
From Equation (1), we see that the radio refractivity consists of a dry and wet part [9-12]:
The modified refractivity is used considering the flat earth, which is related to the refractivity by
Log P, MV= molar volume, MR= molar Refractivity and [pi] = value for Particular Substituent No.
This model uses the wet term of earth refractivity wet N, regarding relative humidity and temperature, averaged at least once a month as input (Agunlejika et al., 2007).
With the aim of making them more visible, the term of refractivity, N, is used [1, 3, 4, 6, 8].
