Geometric standard deviation ÷
WebThe geometric mean is defined as: x 1 ⋅ x 2 ⋅ x 3 … ⋅ x n n. The geometric mean and geometric standard deviation are restricted to positive inputs (because otherwise the answer can have an imaginary component). Hence if any argument is negative, the result will be NA. If any argument is zero, then the geometric mean is zero. WebMar 15, 2011 · The answer above is not advocating that. He's saying you calculate z = ln x, then calculate the arithmetic mean of z, call it z ¯, along with the corresponding confidence interval [ L, U]. The geometric mean is then exp { z ¯ }, and its CI is [ exp { L }, exp { U }]. You can also do this in a regression setting. – dimitriy.

In probability theory and statistics, the geometric standard deviation (GSD) describes how spread out are a set of numbers whose preferred average is the geometric mean. For such data, it may be preferred to the more usual standard deviation. Note that unlike the usual arithmetic standard deviation, the geometric … See more If the geometric mean of a set of numbers {A1, A2, ..., An} is denoted as μg, then the geometric standard deviation is See more The geometric standard deviation is used as a measure of log-normal dispersion analogously to the geometric mean. As the log-transform of a log-normal distribution results in a normal distribution, we see that the geometric standard deviation is the exponentiated … See more The geometric version of the standard score is If the geometric … See more • Non-Newtonian calculus website See more WebMar 27, 2003 · Description: The geometric standard deviation is defined as: For the difference of geometric standard deviations, the geometric standard deviation is computed for each of two samples then their difference is taken.
