Percent Deviation

The Image Processing toolbox toolbox is lacking a key feature I need, namely the support of all data types.Quick list of the source included:imhist_thresh.cpp: Generate histogram from data, # of bins based on unique values.imsmarthist_thresh.cpp: equalize data based on...

Five methods for converting a signal to a binary representation. Methods outlined in Arthur Petrosian, "Kolmogorov Complexity of finite sequences and recognition of different preictal eeg patterns".Methods are:1. average method: sample assigned 1 if above the signal average2. modified zone...

How can we characterize an image, and does the same characterization yield the same result? In this work, we study one possible characterization, distribution metrics. That is, we assume the desired region of interest has a different probability distribution from its corresponding background....

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...

The GUI application plots VLE data of ethanol-water mixture at various pressures. Both Txy and xy diagrams can be plotted at the pressure value specified by the user. The Wilson model allows the program to take into account the deviation from ideal behavior in the liquid phase. User should enter...

In order to optimize any MATLAB function, there are two options: 1) rewrite the function to take only 1 array of inputs, reading all others from a file, perhaps, or from a global variable (undesirable), or 2) write an interface layer that handles this.This function provides an interface layer...

The accompanying code is the simulation of a simplified version of a synfire chain in a cortical network, inspired by the ideas of Abeles (1982, 1991), Bienenstock (1995), and Diesmann et al. (1999). In a synfire chain groups, or pools, of neurons are connected in a feedforward arrangement. The...

This is a companion to Matlab's Statistics toolbox ksdensity function and Philipp Berens' CircStat toolbox.The difference with Matlab's ksdensity function is that this function is adaped to circular data, such as wind orientation. Using Matlab's function will give biased values at the extremities...

An electron gun produces particles with specified rates and random velocities and direction, some of them collide with upper plate that its position and size are defined. This program simulate this process and shows what percent of particles collide with the plate and also show the distribution...

Polar Parallel Coordinate Geometry (PPCG) plots standardardised time series data. Colour is used to demonstrate data through time; black being the oldest to white being the newest. 2 - 3 Std deviation warning/action limits are also highlighted by yellow/red respectively.

Analogous to Matlab trimmean, but trims only the low values. The trim percent applies to the low values only, which is different from the trimmean, where the percent applies to both low and high values, i.e. it is effectively divided by 2 on each end.

This file executes the non parametric Mann-Whitney-Wilcoxon test to evaluate the difference between unpaired samples. If the number of combinations is less than 20000, the algorithm calculate the exact ranks distribution; else it uses a normal distribution approximation. The result is not...

Considering some input arguments, this function performs n simulations with random trades in a price matrix, saving 3 performance indicators (annualized return, annualized standard deviation and annualized sharpe) at each simulationFor example, suppose that you're a trader and have earned 15% of...

This function returns statistics on the intensity of an image, including the sum, mean, standard deviation, min and max. A rectangular region of interest can be selected by the user by using 'r' as the 2nd parameter. Alternatively, the region of interest can be more accurately defined by a...

Embed/Hide one or more images inside one bigger image (source image).Code also tells how much of the source image you are using for embedding and as long as it's less than 100 percent, you can obviously cramp in more images.Hide n seek!!

XC = WILSON(X,N) Returns the center of the Wilson Score Interval for the binomial distribution. X and N are scalars containing the number of successes and the number of trials, respectively. [XC, WSI] = WILSON(X,N,ALPHA) gives the centers and 100(1-ALPHA) percent Score Intervals given the data.
