This GUI uses a constant relative volatility (alpha) to estimate the equilibrium curve. From there, the GUI uses the "McCabe and Thiele Graphical Method" to estimate the ideal number of plates in the column. A reference is provided in the GUI: look in Help/About. Comments, suggestions or bugs, please write to cgelmiREMOVE@gmail.com.

The program computes the number of equilibrium stages for a binary ideal mixture with relative volatility equal to 2.45. The feed is a two phase mixture with a feed quality is equal to 0.85. The distillate, feed and bottom mole fractions are 0.9, 0.5 and 0.1, respectively. The reflux ratio is taken to be 1.51435 . We draw the McCabe and Thiele Diagram and get the number of theoretical plates equal to 9.

This is a free spreadsheet that downloads free historical stock data from the Yahoo database into the spreadsheet and calculates the historical or realized volatility of the selected stock. The standard deviation of prices are plotted along side the stock price chart. The user can freely change the stock used by entering the ticker symbol into the appropriate field and perform a fresh download. Users are also able to change the date range used for the stock data, the number of days back to use for the volatility calculation and the number of volatility days to use..

This code optimises the parameters for the term structure of volatility (TSOV) applied to historical forward curves - see discussion in Harris in reference 1 below. TSOVs avaible are: TermType - 1 = sigma = A exp (-CT) - 2 = sigma = A exp (-CT) + D - 3 = sigma = (A + BT) exp (-CT) + D Required data - Local volatility and return data - both assumed annualised. The optimisation applies the nonlinear least square fitting tool and MLE approach using the fminsearch function - see reference 2. To run type: TSOVControl This code can be used to derive TSOV parameters for the Clewlow and Strickland Forward curve or spot models.

It connects and retrieves data from the Yahoo! finance service. The program uses daily closing prices in the calculations. If not specified, the program defaults to N=20 previous trading days. The user may supply either a single ticker symbol or a cell array of ticker symbols. Using the supplied N, the program will then calculate the historical volatility for each stock..

RPitch is a small, handy feature-rich relative pitch ear training application. It's written in Java and uses the javax.sound.midi API to generate MIDI audio. &Relative pitch& is the ability to recognize and name an interval (the distance between two musical notes) simply by hearing it. Unlike perfect pitch, which many claim cannot by acquired through training or practice, most people can attain a reasonably well-developed sense of relative pitch through practice and repeated drills..

Scroll Bars script returns a value relative to the scroll bar slider position which can be used to control the value, position or other attributes of an elements. The scroll bar can include a slider and left and right scroll buttons. This script addresses four types of scroll bars: - No Slider or Scroll Buttons. - Slider but no Scroll Buttons. - Slider and Right Scroll Button but no Left Scroll Button. - Slider and Left Scroll Button but no Right Scroll Button. - Slider, Right Scroll Buttons and Left Scroll Button. A value between 0 and a specified maximum relative to the clicked or slider position is passed to a specified function as the first argument together with the slide bar object as the second argument.

This is a jQuery plugin to center an element bigger than its container by using the CSS relative position Default behavior is to align an image top left. If per example, an image is 800 pixels and the container is 600 pixels, the image will hover on the righ, outside the container. This plugin centers the image on the same line with the container, so the image is now 100 pixels outside on both sides. This enhances the design, by not providing choppy break points..

It is a Matlab function that determines the zero of a regular real function. zero=newton_raphson(function,error) The function has two input variable: 'function' is a string that represents the function of which find the relative zero. It must be expressed with the real variable 'x'. 'error' is the tolerance for the algorithm's arrest. The function returns the zero point of the real function. It plots, in a figure, the function and the tangents used for the search of the zero..

The Toolbox forecasts the volatility of a (mxn) vector of data and from a variety of in-built / non-in-built GARCH models with various distributions, as well as the univariate RiskMetrics. The toolbox also estimates a number of Volatility Forecast Loss Functions and if selected Value-at-Risk for both short and long positions, along with a number of back-tests. The three main functions are the following: VFMatlab.m: In-built Matlab functions (i.e. models: GARCH, GJR-GARCH and EGARCH, distributions Normal and Student's t-Distribution) VFGarch.m: Forecasts the volatility of the following models and distributions: The supported models are: GARCH, GJR-GARCH, EGARCH, NARCH: Nonlinear ARCH: Engle and Bollerslev (1986) NGARCH: Nonlinear GARCH: Higgins and Bera (1992) AGARCH: Asymmetric GARCH: Engle (1990) APGARCH: Asymmetric Power GARCH:...

The self-contained script demonstrates excess, volatility driven growth, in a rebalanced portfolio. Based on the paper "Benchmarking and Rebalancing" by Gabay and Herlemont, yats.com, 19 Septembre 2007, this script reproduces example 1, showing the long-term rebalancing excess growth rate g*. There is an apparent paradox when considering a portfolio of risky assets that by rebalancing between them in constant proportions, under certain conditions, one can observe excess long-term growth above the expected best buy and hold strategy. This script reproduces previous known work and can act as a starting point for people interested in examining this in more detail.
