WebApr 23, 2024 · Geometric Brownian motion X = {Xt: t ∈ [0, ∞)} satisfies the stochastic differential equation dXt = μXtdt + σXtdZt. Note that the deterministic part of this equation … Thus, the geometric standard deviation may be more appropriately called geometric SD factor. [1] [2] When using geometric SD factor in conjunction with geometric mean, it should be described as "the range from (the geometric mean divided by the geometric SD factor) to (the geometric mean multiplied by the … See more 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 … 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 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 version of the standard score is $${\displaystyle z={{\ln(x)-\ln(\mu _{g})} \over \ln \sigma _{g}}={\log _{\sigma _{g}}(x/\mu _{g})}.\,}$$ See more • Non-Newtonian calculus website See more
