WebJan 19, 2024 · A lognormal distribution is a result of the variable “ x” being a product of several variables that are identically distributed. It is common in statistics that data be normally distributed for statistical testing. The lognormal distribution can be converted to a normal distribution through mathematical means and vice versa.
Web1 Answer Sorted by: 2 Let X ∼ log N ( μ, σ 2). The median is e μ = 0.5, so μ = log ( 0.5). As X is lognormal, then Y = log X has the normal distribution N ( μ, σ 2). Then we calculate 0.98 = P ( X < 2.3) = P ( log X < log 2.3) = P ( Y < log 2.3) = P ( Y − μ σ < log 2.3 − μ σ). city of vista employmentWebA lognormal (or log-normal) distribution is a continuous probability distribution.
