Data Analysis

KyPlot supports the following methods of data analysis.

Measurement of amplitudes and areas of peaks  NEW

Amplitudes and areas of peaks in signals can be interactively measured.

2D Fourier transform  NEW

KyPlot now supports calculation of 3D fast Fourier transform and outputs as graphs or images.

Spreadsheet calculations with mathematical formulas (Excel compatible)

Removal of linear trend and numerical filtering for time series data

Numerical differencing, differentiation and integration

Creation of histograms, cumulative distributions, regressograms and density plots

Matrix and vector operations

Numerical solutions of algebraic equations, nonlinear equations and differential equations

Numerical integration of functions

Nonlinear least squares estimation and maximum likelihood estimation

Linear/quadratic programming and unconstrained or constrained linear least squares estimation

Numerical deconvolution

Fourier transforms

Spectral analysis

(estimation of autoconvariance and spectral density functions by FFT, Blackman-Tukey method or AR models)

Time series analysis

(ARM model, seasonal adjustment model, time-varying variance estimation, time-varying coefficient AR model, locally stationary AR model and change point estimation)

Gabor (Short-time Fourier) transform

Wavelet analysis

(discrete and continuous wavelet transforms and wavelet thresholding)

Simulation of random data
