Sorted by: 2. First of all, the pdf of X should be of the form. f ( x) = 1 σ ⋅ exp ( − x − μ σ) [ 1 + exp ( − x − μ σ)] 2, x ∈ R. where μ is real and σ is positive. Normalising the pdf by taking Y = ( X − μ) / σ, we get the standard logistic pdf. g ( y) = e − y ( 1 + e − y) 2, y ∈ R. Now, karith foster book
