EViews.com

Hi

i want to make my estimations with variables in log, when i generate the variables with eviews, they are differents wih those calculated with excel...... so what is the right to use????

thanks for help..i need it to pursue my work ..please!

The Log command in EViews computes the natural log. I believe in Excel it computes log to the base 10.

so I better use the eviews log ???

It really does not matter. The ratio between these two logarithms is fixed, and therefore they do the same job. If you are planning to use EViews extensively in your study and export the results to Excel, then it will be more convenient to use the natural logarithm.

Excel's log(x) is equal to EViews' @log10(x) and
Excel's ln(x) is equal to EViews' @log(x)
