A modified intervention model for gross domestic product variable (agriculture)

An Intervention Analysis Of The Behavior Of The Iranian Real Gross Domestic Product: 1959-2001

Estimation of Gross Domestic Product of Iran (1906-1935)

This paper provides a brief technical survey of the historical national accounts of Iran. Gaining access to longer-term time series in compliance with concepts, classifications and standards comparable to the present one help fulfill quantitative studies in the area of business cycles. Despite the shortage of reliable, standardized and classified information, the methodology applied in thi...

Vector Autoregressive Model Selection: Gross Domestic Product and Europe Oil Prices Data Modelling

 We consider the problem of model selection in vector autoregressive model with Normal innovation. Tests such as Vuong's and Cox's tests are provided for order and model selection, i.e. for selecting the order and a suitable subset of regressors, in vector autoregressive model. We propose a test as a modified log-likelihood ratio test for selecting subsets of regressors. The Europe oil prices, ...

Modified mathematical model for variable fill fluid coupling

Variable fill fluid couplings are used in the speed control units. Also, variation in coupling oil volume is used in adapting one size of coupling to a wider range of power transmission applications. Available model for the partially filled fluid couplings, has a good performance for couplings with fixed amount of oil but their performance will be degraded if they are used for the variable fill...
