Transformation into normal distribution in Eviews

[vazirova]

Hello! When I was estimating my model it turned out that one parameter in time series (oil price) does not have a normal distribution.
I've read that there exists Box-Cox transformation and it is somehow possible to apply it in Eviews.
But it is necessary to calculate special Box-Cox parameter and I don't know how to do it in Eviews
I would be very grateful for your help!
