What is the domain of natural log?

The logarithm base e is called the natural logarithm and is denoted ln x. Logarithmic functions with definitions of the form f(x)=logb x have a domain consisting of positive real numbers (0,∞) and a range consisting of all real numbers (−∞,∞).

What does natural logarithm do?

The natural log is the logarithm to the base of the number e and is the inverse function of an exponential function. Natural logarithms are special types of logarithms and are used in solving time and growth problems. Logarithmic functions and exponential functions are the foundations of logarithms and natural logs.

What happens when you take the natural log of a number?

If you take the log of a number, you're undoing the exponent. The key difference between natural logs and other logarithms is the base being used. Logarithms typically use a base of 10 (although it can be a different value, which will be specified), while natural logs will always use a base of e.

Why do we use natural log in regression?

We prefer natural logs (that is, logarithms base e) because, as described above, coefficients on the natural-log scale are directly interpretable as approximate proportional differences: with a coefficient of 0.06, a difference of 1 in x corresponds to an approximate 6% difference in y, and so forth.
