Deviation

Calculates the min and max of a positive triangular distribution given a standard deviation (sigma) and assuming the mode = 1.This function can handle single value,vector or matrix inputs of sigma. For sigma > 1/sqrt(6), the distribution will be asymmetrical with minimum = 0 and mode = 1. Platforms: Matlab

This function implemented by function 'copula111cGarch111VaR' and other related functions that will estimate the value at risk of portfolio.The marginal model are GARCH(1,1),GJR(1,1),AR(1)-GARCH(1,1)and AR(1)-GJR(1,1)the parameters and standard deviation of models will used for estimation of...

Estimates the noise standard deviation from an (MRI) image (2D) corrupted with Rician noise based on the skewness of the distribution. This method doesn't depend on the background for noise estimation. Can be used for MR images with and without background.Ref: Jeny Rajan, Dirk Poot, Jaber Juntu... Platforms: Matlab

This code calculates the Exponentially Weighted Moving Average Standard Deviation Exponentially weighted moving average (EWMA) standard deviation applies different weights to different returns. More recent returns have greater weight on the variance. The exponentially weighted moving average... Platforms: Matlab

Fits a Gaussian curve to data points. You can specify your initial values for amplitude, mean and standard deviation, or it will guess them. Platforms: Matlab

QUADTREESEG - mex implementation (compile by mex quadtreeseg.cpp). Also an equivalent MATLAB implementation is present in zip file.Segments an image by recursively dividing it into four equal blocks if the variability in its pixels is greater than a certain amount. The image input is usually... Platforms: Matlab

Shade Anomaly fills in graphs above and below the x-axis different colors. It allows you to create offsets, so that values above a certain threshold are shaded. This is good to use if you would like shade values above a standard deviation.There is an example in the script if you do not enter any... Platforms: Matlab

Fits Gaussian curve into pointsThe function fits Guassian probability density function into a set of points. Standard deviation and mean are returned. Platforms: Matlab

This file calculates the Sortino ratio of an investment asset, portfolio or strategy. The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target.... Platforms: Matlab

This function generates an overlapping histogram of multiple populations. For a demo simply type "histn".SYNTAX: h=histn(Y,X,S)Y - Data array that is NxM where N is the number of groups and M is the number of measures within each group. Right now M has to be the same for each group.X - Optional... Platforms: Matlab

The result will be displayed in a matrix format.For uniform distributions,the values returned by the MATLAB function rand() are multiplied by (b-a), then added to a.For normal distributions the output of randn() is multiplied by the standard deviation (b), and then added to the desired to the...

WebServer Sentry allows monitoring of clients making requests of your web server.It has trigger points which you set that causes a change in colour if clients trend too high and the IP address is blocked. Code injection is detected and IP is also.Features:- Block SQL, Code Injection and Denial of... Platforms: PHP

For a spreadsheet with real valued data, this script calculates the mean, variance and standard deviation of each row, creating a new spreadsheet with the respective row statistics. Platforms: Mac

Growth Curve is a simple software which allows to build microorganism growth curves in the logarithmic scale. It estimates medium doubling time and it's standard deviation. All curves are proposed to be the duplications of one experiment. Platforms: Mac

This is a command-line application that gives the mean and standard deviation at various site(s) for specified IMT(s), attenuation relationship(s), and for each earthquake rupture in one of three Earthquake Rupture Forecasts (ERFs). The ZIP file for the application contains an executable Java JAR... Platforms: Mac

Assume that you have a list of vectors v_1, v_2, v_3, ..., v_n and an equally sized list of vectors w_1, w_2, ..., w_n. A way to quantify how similar these lists are to each other is to compute the sum of the squared distances between the vectors: sum((w_1 - v_1)**2 + ... + (w_n - v_n)**2). In... Platforms: *nix
