InverseLogNormal[ <Mean>, <Standard Deviation>, <Probability> ]
Computes the inverse of cumulative distribution function of the log-normal distribution at probability p, where the log-normal distribution is given by mean μ and standard devation σ.
In other words, it finds t such that P(X ≤ t) = p, where X is a log-normal random variable.
Probability p must be from [0, 1].
Examples:
  • InverseLogNormal[10, 20, 1/3] computes 3.997.
  • InverseLogNormal[1000, 2, 1] computes \mathrm{\mathsf{ \infty }}.
