TRAMO ("Time Series Regression with ARIMA Noise, Missing Observations and Outliers") (Gómez y Maravall, 1996) is a program for estimation, forecasting, and interpolation of regression models with missing values and ARIMA errors, in the presence of possibly several types of outliers (no restriction is imposed on the ___location of the missing observations in the series). The program can be run in an entirely automatic manner.
