Predicting Transformed Dependent Variable Listen Data

For the purposes of modeling, which logarithm you use—natural logarithm, log base 10 or log base 2—is generally not critical. In regression, for example, the choice of logarithm affects the magnitude of the coefficient that corresponds to the logged variable, but it doesn’t affect the value of the outcome. I like to use log base 10 for monetary amounts, because orders of ten seem natural

This is useful to me because of the log rule that says that exponents inside a log can be turned into multipliers in front of the log: log b ( m n ) = n · log b ( m ) When I take the log of both sides of an equation, I can use any log I like (base- 10 log, base- 2 log, natural log, etc), but some are sometimes more useful than others.
