To test for cointegration of the logarithms
of the real exchange rates, consider the following unrestricted autoregressive model with an intercept, white noise errors, and a deterministic trend:
The connections of slide rules with logarithms
(which might have explained how they actually worked) were very rarely highlighted, at least in my recollections of my own experience.
The results of estimating dynamic model showed that the variables oftrade liberalization logarithm
with one and two lags have positive effect on stock indices, while the logarithm
of the oil price and its one lag has a negative effect on the stock index.
From different results above, we remark that return on assets is positively correlated with logarithm

Luay Al-Zibaidi, in collaboration with an Austrian research team of the Faculty of Medicine at the University of Vienna, obtained a patent on inventing a logarithm
to calculate and gauge blood pressure during open heart operations through inserting an air balloon into the coronary, where blood pressure would be controlled via an instantaneous continuous calculation of the blood pressure inside the coronary, then controlling air quantity inside the balloon to acquire a steady blood pressure, during the heart operation through using the invented logarithm
Time-Tech] cover a wide range, we use a logarithm
