The Use of the Lognormal DistributionIndividual values are logarithmically transformed for the use of the lognormal distribution. The type of logarithm is of no importance, and either the natural logarithm, which is based on the natural number e=2.7183 (thus x is transformed to ln x), or the decimal logarithm to the base 10 (thus x is transformed to log x) can be used..作者: CHIP 時(shí)間: 2025-3-25 00:45

The Normal Distributionistribution since it was derived by C. F. Gauss and included in his work about the theory of measurement of errors.

Standard Deviation and Variance of the Meanmean value for the population. If several samples are taken from the population, then the mean values of these samples will vary, and a standard deviation can also be calculated for this variation. It is known as the standard deviation of the mean (or the standard error of the mean) or the variance 作者: 審問(wèn) 時(shí)間: 2025-3-28 10:56

Further Statistical Considerations for Evaluating Mineral Depositsve established a number of statistical factors derived over years of experience, and these factors should be taken into consideration.

Bias in Reserve Calculationse incorporated into the computations. One is often unaware that this might have happened. In the example of a lateritic nickel deposit, as described in Chapter 4.1 (Economic Evaluations in Exploration), a bias to higher nickel grades was caused by incorrect weighting.作者: LUMEN 時(shí)間: 2025-3-29 16:59 作者: PSA-velocity 時(shí)間: 2025-3-29 22:13
