data setsThis chapter describes the use of statistical regression techniques to develop pedotransfer functions (PTFs) estimating hydraulic properties from basic soil properties. PTFs are considered as regression
We present here annotated MATLAB scripts (and specific guidelines for their use) for Q-mode factor analysis, a constrained least squares multiple linear regression technique, and a total inversion protocol, that are based on the well-known approaches taken by Dymond (1981), Leinen and Pisias (...
Statistical analysis software with proven, validated models. Analyze any kind and size of data using the latest statistical analysis techniques. SAS/STAT statistical software includes exact techniques for small data sets, high-performance statistical modeling tools for large data tasks and modern methods...
Statistical Data Analysis Statistical analyses and modeling often focus on “hypothesis testing” and “parameter estimation.” For example, in multiple regression, the parameters of a linear model are estimated that predict some outcome or response variable y as a linear function of the available pre...
For some data sets, the calculations for the first approach are simple enough to do by hand. The second approach that we consider assumes that computer software for general analysis of variance is available. Such analysis of variance software should cope with missing values via a regression ...
Statistical AnalysisConcepts Statistical Analysis Confidence Bands: An Essential Tool for Statistical Analysis Published: October 19, 2024 by Ken Feldman The concept of a confidence band is usually associated with regression analysis. We will also explain why a confidence band is not the same as ...
Work with curve fitting and data analysis projects by modeling structures and environments based on input data and modifying output results with linear regression models, nonlinear regression models, smoothing methods, or various kinds of splines. Data comparison operations are available. CurveExpert is ...
the third part features new chapters on mixed logit models, logistic regression, and ordered probability models. The last section provides additional coverage of Bayesian statistical modeling, including Bayesian inference and Markov chain Monte Carlo methods. Data sets are available online to use with ...
Nonlinear regressionOutliersPedigree analysisRegressionRepeated-measures dataThe t distribution provides a useful extension of the normal for statistical modeling of data sets involving errors with longer-than-normal tails. An analytical strategy based on maximum likelihood for a general model with ...
