Suppose we are estimating the model: ln Y = a + b ln X The relation between natural (ln) and base 10 (log) logarithms is ln X = 2.303 log X . Hence the model is equivalent to: 2.303 log Y = a + 2.303b log X or, putting a / 2.303 = a*: log Y = a* + b log X WitrynaIn mathematics, the logarithmic mean is a function of two non-negative numbers which is equal to their difference divided by the logarithm of their quotient.

But the logarithm of that ratio is a negative number that can have a huge modulus, and then it makes a big bonking difference for the mean of the logarithms. … WitrynaLogarithm is based on the combination of two Greek words: logos and arithmos (number).
