A highly sensitive gas-liquid chromatographic method with electron capture detection of clonidine in plasma is described. The alkaline samples (100-200mul) are extracted into cyclohexane-butanol (9:1), re-extracted into 0.1 N sulphuric acid, made alk

Transfer function models can be used to model the relationship between leading indicators and the business cycle. The traditional transfer function approach assumes that the pure delay (lead) as well as the other parameters of the model are constant.

The Swedish unemployment rate is forecast using three time series methods: the ARIMA, transfer function and Vector Autoregressive (VAR) models. Within this context, the choice of modelling strategy is discussed. It is found that the forecasting perfo

In this paper ridge estimators are used to obtain preliminary estimates of the impulse response weights in the Box-Jenkins transfer function model. Five ridge estimators and the Equity estimator are evaluated in a Monte Carlo study covering 5000 diff

In this paper different ways to identify the order of the Box–Jenkins transfer function model are discussed. The discussion concerns estimation of the impulse response weight function in the case of more than one input variable. It is found that mo
