- 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 \infty .
