Caption: Figure 7: Comparison between empirical distribution of the input power delivered to the mobile phone during pure NLOS scenario and a log-normal distribution
To model the reporting delay for each disease, we fitted analytical log-normal distributions
to the OSIRIS data.
For this reason,  and  resort to the log-normal distribution
, and use it to approximate the Gamma-log-normal distribution in (6) and derive the closed-form PDF of [p.sub.i].
three-parameter shifted lognormal distributions , the truncated-stable distributions considering three types of secondary spatial reuse protocols , the log-normal distribution
under power control and contention control , the symmetric stable distributions , the Levy distribution for some conditions , and the Gaussian distribution .
In order to account for variations in the sensitivity of the cells to radiation, one could assume that the individual radiation sensitivity of the cells in a population follows a given log-normal distribution
The log-logistic (LL) distribution is widely used in practice And it is an alternative to the log-normal distribution
since it presents a failure rate function that increases, reaches a peak after some finite period, and then declines gradually.
Furthermore, the free-flow travel time distribution of the highway from the peripheral parking lots to the destination is assumed to follow a log-normal distribution
where: D is the specific distribution form of [lambda], such as normal, uniform or log-normal distribution
; n and a are the mean and standard deviation of [lambda], respectively.
The clustering of FZI data is performed on the basis of the logarithm of FZI values because the FZI values calculated from actual field data usually exhibit a log-normal distribution
. Because the FZI distribution is a superposition of multiple log-normal distributions
, a histogram of log FZI values should show N number of normal distributions for N number of HFUs.
The median normal deviation of the log-normal distribution
([sigma]) was calculated from the median [CV.sub.t] (as a decimal value), as: [sigma] = [[square root of ([CV.sup.2.sub.t] + 1)] (Eq.
Therefore, log-normal distribution
was selected as a suitable model to represent data sets for motorized 2-wheelers.
