TSP International was named for its Time Series Processor, an econometric software package, which includes standard estimation methods, forecasting and a flexible language for programming. TSP is a complete language for the estimation and simulation of econometric models. Its features include: easy-to-use free format command and data input; standard econometric estimation methods, such as OLS, instrumental variables, LIML, nonlinear systems, generalized methods of moments, FIML, maximum likelihood for qualitative dependent variable models, ARIMA, kalman filter, ARCH and other time series techniques; extensive diagnostics and testing facilities; flexible data transformation with many built-in functions and matrix algebra; and it offers a choice between interactive use or full programming language for econometric methods development. Common applications include applied econometrics, macroeconomic research and forecasting, sales forecasting, financial analysis, cost analysis and forecasting, Monte Carlo simulation, estimation and simulation of economic models. TSP was founded in 1978 and is located in Palo Alto, Calif.
