In this paper we give explicit expressions for the forecasts of levels of a vector time series when such forecasts are generated from (possibly cointegrated) vector autoregressions for the corresponding log-transformed time series. We also show that simply taking exponentials of forecasts for...

In the globalized world of 21st century, the world order has become dynamic. But the parameters of success are same. A country having only internal success cannot sustain for long and similarly for external success. External success is largely dependent upon exchange rate movements and its...

In this paper we give explicit expressions for the forecasts of levels of a vector time series when such forecasts are generated from (possibly cointegrated) vector autoregressions for the corresponding log-transformed time series. We also show that simply taking exponentials of forecasts for...

This paper applies the Inverse Hyperbolic Sine (IHS) transformation to explore the variables that determine a firm’s R&D collaborative expenditure. The IHS specification is used to overcome the inconsistencies deriving from non-normality of error terms which are typical in censored data. This...
