Consequently, if instead of the original parameters the logarithms of the parameters follow a Gaussian distribution, now one gets the Log-Normal distribution
instead of the normal (Gaussian) one.

first-order kinetic model for copper (II)-humic acid complex dissociation.
5(a) and (c)] with that of the log-normal distribution
, given in Figs.
For comparison, the size distribution parameters for planar crystals if one or two log-normal distributions
were assumed were calculated.
Relative to a log-normal distribution
, a positive kurtosis implies a greater probability of relatively small outcomes as well as a greater probability of extreme outcomes.
Contrary to this general impression, the results of our study support the assumptions behind the model that the behaviour of stock prices at the Karachi Stock Exchange can be modelled by a time-continuous and continuous-variable stochastic process which has a log-normal distribution
, and short-term predictions about the prices can be made by a careful estimation of model parameters.
The distribution of permeability in porous media has been usually reported to approximate a log-normal distribution
(Freeze, 1975; Sudicky, 1986).
The lowest Standard Error was obtained from the 2-parameter Log-Normal distribution
The log-normal distribution
endpoints were also inflated, by ~250%.
Based on the above reasons, it was concluded that the log-normal distribution
is appropriate to model the distribution of microvoids, and the microvoids in this heterogeneous process depend on the rubber particle size distribution.
These distributions are combined into an overall log-normal distribution
for the threshold dose (dose below which there is no contribution to a toxic response) by assuming the variables act independently and multiplicatively.
