XLfit was validated by The UK National Physical Laboratory [3] in 2004; the unit tests for this are provided in the model editor from version 5.4 onwards to allow each version to be easily validated. XLfit was used by NASA to analyze the battery life of the Curiosity Mars Lander. [4]
Genedata – software for integration and interpretation of experimental data in the life science R&D; GenStat – general statistics package; GLIM – early package for fitting generalized linear models; GraphPad InStat – very simple with much guidance and explanations; GraphPad Prism – biostatistics and nonlinear regression with clear ...
RAM models return standardized and raw estimates, as well as a range of fit indices (AIC, RMSEA, TLI, CFI etc.). Confidence intervals are estimated robustly. The program has parallel processing built-in via links to parallel environments in R, and in general takes advantage of the R programming environment. Users can expand the package with ...
jamovi is an open source graphical user interface for the R programming language. [3] It is used in statistical research, especially as a tool for ANOVA (analysis of variance) and to understand statistical inference. [4] [5] It also can be used for linear regression, [6] mixed models and Bayesian models. [7]
TableCurve 2D is a linear and non-linear Curve fitting software package for engineers and scientists that automates the curve fitting process and in a single processing step instantly fits and ranks 3,600+ built-in frequently encountered equations enabling users to easily find the ideal model to their 2D data within seconds.
R package. Fit unidimensional item response theory (IRT) models to mixture of dichotomous and polytomous data, calibrate online item parameters, estimate examinees' latent abilities, and examine the IRT model-data fit on item-level in different ways as well as provide useful functions related to unidimensional IRT.
IGOR Pro is a scientific data analysis software, numerical computing environment and programming language that runs on Windows or Mac operating systems. It is developed by WaveMetrics Inc., and was originally aimed at time series analysis, but has since then evolved and covers other applications such as curve fitting and image processing.
The general ARMA model was described in the 1951 thesis of Peter Whittle, who used mathematical analysis (Laurent series and Fourier analysis) and statistical inference. [12] [13] ARMA models were popularized by a 1970 book by George E. P. Box and Jenkins, who expounded an iterative (Box–Jenkins) method for choosing and estimating them. This ...
