Matrixer is a piece of software especially suited for teaching econometrics and doing medium-scale applied research. It is small (in physical size, not in capabilities) and has smooth interface. Many routine operations could be done in seconds.
The program provides many classical as well as more recent econometric techniques and models
Binomial logit and probit
Censored (tobit) and truncated regression
Poisson and negative binomial regressions
Regression with multiplicative heteroskedasticity
Regression with ARMA errors
Box-Jenkins model (ARIMA) with dynamic forecasts
ARFIMA-FIGARCH (long-memory models)
(Generalized) instrumental variables estimator
Nonparametric density estimation
Simultaneous equations, 2SLS, 3SLS and FIML
Nonlinear instrumental variables method
Method of maximum likelihood
The program includes many other helpful features to handle and analyze data
Descriptive statistics (mean, variance, etc.)
Various data plots
Visual data description (histogram, spectral density estimate, autocorrelation function)
Table of correlations between variables
Probability calculator (normal, Student t, chi-square, Fisher F)
Dickey-Fuller test (additional files are needed)
Vector and matrix operations (that is why it was called Matrixer).
Small build-in programming language for writing macros
Fast drawing of function plots according to formulas
Powerful data import from text files (download examples)
Data export to several popular formats

The current version of Matrixer is free for non-commercial use. One can download and run it freely. So in fact there is no registration. However, Matrixer costs a lot of time to produce, so, please, pay for it if you’ll use it for a long enough time and find it helpful. Consider this as philanthropy (scientific grant).
The fee is $40. Payments are made through RegSoft.com payment processing service.
The project started in 1994 when Alexander Tsyplakov was a student of Novosibirsk State University. The reason for starting Matrixer was a dissatisfaction with Statgraphics which was at that time the only statistical program available to the author.
Matrixer was used by the author to do his own research on Russian inflation and to teach econometrics in Novosibirsk.
The first versions ran under MS DOS. There was some experience with free English DOS version of Matrixer. One may find some traces of it in the depth of Internet.
