4.2 Mean or Expected Value and Standard Deviation
WebMar 11, 2024 · mu = log ( (m^2)/sqrt (v+m^2)); sigma = sqrt (log (v/ (m^2)+1)); Now, this is clear for me but the confusing part in the document is the following sentence "If X is distributed lognormally with parameters µ and σ, then log (X) is distributed normally with mean µ and standard deviation σ" WebTo find the expected value, E (X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as E(X) = μ = ∑xP(x). dmv registration lookup tx
