In page Log-normal distribution:

"
  • For highly communicable epidemics, such as SARS in 2003, if public intervention control policies are involved, the number of hospitalized cases is shown to satisfy the log-normal distribution with no free parameters if an entropy is assumed and the standard deviation is determined by the principle of maximum rate of entropy production.[4]
  • The length of inert appendages (hair, claws, nails, teeth) of biological specimens, in the direction of growth.[citation needed]
  • The normalised RNA-Seq readcount for any genomic region can be well approximated by log-normal distribution.
