• There is definitely a pattern in the number of records exposed by data breaches, and it follows a so-called lognormal distribution.

• Similar considerations suggest that the form of the stochastic process distribution, whether it is normal, lognormal, or otherwise, is superfluous.

• The range of values for R and D are assumed to be represented by lognormal distribution curves (See Figure 1).

• The equations for f and a are derived using the lognormal distribution curve S (Figure 2) along with statistical mathematics and algebra.

• A convenient way to assess the probability of failure (D R) is to consider a single lognormal distribution curve called the safety margin or S, where S = R – D (see Figure 2).

• Geometric Brownian motion, in contrast, is such that each random variable St has a lognormal distribution.

• A piece of supporting evidence is that several evolutionary mechanismstend to be stochastic processes, whichmeans their behaviour could be potentially represented by distribution curves (normal, lognormal, or other).

• We also show that the latent and infectious periods can be approximated by using lognormal distributions with means (SD) of 4.3 (1.8) and 2.5 (1.2) days.

• Even I know these are very large numbers, so I look around for reasons thank you google and I hit upon the possibility I could be looking at a lognormal distribution.

• We propose that the distribution of DNA words in genomic sequences can be primarily characterized by a double Pareto-log normal distribution, which explains lognormal and power-law features found across all known genomes.
