8. Logarithm
   A particular mathematical transformation often used to express economic variables. Advantages: 1) If a variable grows at a constant percentage rate over time, the graph of its logarithm is a straight line. 2) A small change in the logarithm of a variable is approximately its percentage change.

9. logarithm
   logarithm (log'uri&thstrok;um) [Gr.,=relation number], number associated with a positive number, being the power to which a third number, called the base, must be raised in order to obtain the given positive number. For example, the logarithm of 100 to the base 10 is 2, written log10 100=2, sinc...

10. Logarithm
    The common logarithm of a number is the index of the power to which 10 must be raised to be equal to the number. Thus lO to the power of 3 equals lOOO, so that the logarithm of 1000 (usually written log. 1000) is 3. It is evident that the logarithm of any number greater than 1 and less than 10 is fr...

11. logarithm
    Type: Term Pronunciation: log′ă-ridhm Definitions: 1. If a number, x, is expressed as a power of another number, y, if x = yn, then n is said to be the logarithm of x to base y. Common logarithms are to the base 10; natural or Napierian logarithms are to the base e, a mathematical constant.

12. logarithm
    The exponent or index of a number to a specified base – usually 10. For example, the logarithm to the base 10 of 1,000 is 3 because 10³ = 1,000; the logarithm of 2 is 0.3010 because 2 = 10^0.3010. The whole-number part of a logarithm is called the characteristic; the fractional p...
