Software Listing: Linear Regression

The non-linear regression problem (univariate or multivariate) is easily posed using a graphical user interface (GUI) that solves the problem using one of the following solvers: - nlinfit: only univariate problems. - lsqnonlin: can deal with multivariate problems (more than one dependent fitting variable, ydata is a matrix). - patternsearch: this solver is useful to obtain a good start point, before using nlinfit or lsqonolin; this way, the global minimum is determined easier. Data is introduced in the GUI as vector or matrix from the workspace. The model to be fitted must be written in an M-file in vectorized form: ypred = model(x,xdata) ypred is a column vector (univariate problem) or matrix (multivariate problem) with the model response (observations in rows).

Calculates slope and intercept for linear regression of data with errors in X and Y. The errors can be specified as varying point to point, as can the correlation of the errors in X and Y. The uncertainty in the slope and intercept are also estimated. This follows the method in D. York, N. Evensen, M. Martinez, J. Delgado "Unified equations for the slope, intercept, and standard errors of the best straight line" Am. J. Phys. 72 (3) March 2004. The package includes an example and a Monte Carlo simulation verifying the estimated uncertainties. For more info, visit http://blog.nutaksas.com.

Quantile Regression USAGE: [p,stats]=quantreg(x,y,tau[,order,nboot]); INPUTS: x,y: data that is fitted. (x and y should be columns) Note: that if x is a matrix with several columns then multiple linear regression is used and the "order" argument is not used. tau: quantile used in regression. order: polynomial order. (default=1) nboot: number of bootstrap surrogates used in statistical inference.(default=200) stats is a structure with the following fields: .pse: standard error on p. (not independent) .pboot: the bootstrapped polynomial coefficients. .yfitci: 95% confidence interval on polyval(p,x) Note: uses bootstrap on residuals for statistical inference.

This Simulink library is a collection of blocks that perform Parameter Identification through the most rewarded frequency and time domain linear regression methods. It works in Matlab 5.3.1 as well as in later versions. Main examples are: -) Recursive Least Squares (RLS). -) Simple Windowed Regression (LLS). -) Local Weighted Regression (LWR). -) Fourier Transform Regression (FTR). Two example on Linear and Nonlinear Aircraft Parameter Identification are included in the library. IMPORTANT, all of these blocks REQUIRE SMXL (the Simulink Matrix Library) freely available in the File exchange section of the MATLAB Central website.

This routine calculates the median squared error of a linear function, and can be used with fminsearch as a robust linear regression (see help LinearMedianSquaredError). It should be very easy to extend the example code to handle nonlinear functions and to minimize other error functions (least absolute error, for instance)..

Helps choose a Box-Cox power transformation for a multivariate linear regression. Assume you are looking at the residuals of [b,bint,r] = regress(y,X) and it seems a transformation is in place. Use: boxcoxlm(y,X) to find the best lambda for a Box-Cox power transformation (y^lambda, or log(y) for lambda=0) The function will also plot the Maximum Log-Likelihood as a function of lambda, and a 95% confidence region for the best value of lambda More control can be obtained using: [LambdaHat,LambdaInterval]=boxcoxlm(y,X,PlotLogLike,LambdaValues,alpha) which allows ommiting the plot, a different region or precision, and a different alpha value for the confidence interval.

Comparision of simple linear regression equations without data. As well as the before file arsos.m this procedure is suffice to test the homogeneity of k regression coefficients (Ho: b1 = b2 =...= bk). It do not needs to input data, but the sample statistics as sample size, regression coefficients, means and variances. The variability among the regression coefficients requires the F-statistic. If the null hypothesis is rejected, it can proceeds with a Tukey's q multiple comparision test to determine which of the k slopes differ from which other. If the null hypothesis is not rejected, the file test through a F-statistic whether they have equal elevations.
