SHAZAM is a comprehensive computer program for econometricians,
statisticians, biometricians, sociometricians, psychometricians,
politicometricians and others who use statistical techniques.
Currently, SHAZAM is used in 89 countries from the Northernmost (University
of Tromso, Norway) to the Southernmost (University of Otago, New Zealand)
Universities in the world and in Antarctica.
The primary strength of SHAZAM is for the estimation and testing of many types of
regression models. The SHAZAM command language has great
flexibility and provides capabilities for programming procedures.
SHAZAM has an interface to the GNUPLOT package for high
quality graphics.
SHAZAM includes features for:
- data transformations, handling missing observations, matrix manipulation,
evaluation of derivatives and integrals, data sorting,
computation of cumulative distribution functions for a variety of
probability distributions;
- descriptive statistics, calculation of price indexes,
moving averages, exponential smoothing, seasonal adjustment,
financial time series, ARIMA (Box-Jenkins) time series models,
Dickey-Fuller and Phillips-Perron unit root tests,
tests for cointegration, nonparametric density estimation;
- OLS estimation, restricted least squares, weighted least squares,
ridge regression, distributed lag models, generalized least squares,
estimation with autoregressive or moving average errors,
estimation with heteroskedastic errors, ARCH and GARCH models,
Box-Cox regressions, probit models, logit models, tobit models,
estimation using regression quantiles (including MAD estimation),
regression with non-normal errors (including exponential regression,
beta regression and poisson regression), regression with time varying
coefficients, nonparametric methods, generalized entropy methods,
fuzzy set models;
- linear and nonlinear hypothesis testing, calculation of confidence
intervals and ellipse plots, computation of the Newey-West autocorrelation
consistent covariance matrix, regression diagnostic tests
(including tests for heteroskedasticity, CUSUM tests, RESET specification
error tests), computation of p-values for many test statistics
(including the p-value for the Durbin-Watson test), forecasting;
- nonlinear least squares, estimation of systems of linear and
nonlinear equations by SURE, 2SLS and 3SLS, generalized method of
moments (GMM) estimation, pooled time-series cross-section methods;
- principal components and factor analysis, principal components

functions, solving nonlinear simultaneous equations.
