If f = F′ is the density of a random variable X with distribution function F and f is positive and smooth, Lin’s condition is defined as follows: −xf′ (x)/f(x) ↗ ∞ as x → ∞. This condition is essentially involved, together with other conditions such as divergent Krein integral or fast growth rate of the moments, in deciding whether or not F is unique in terms of its moments (Mdeterminate) or non-unique (M-indeterminate). We analyze frequently used non-linear functional transformations of X and clarify whether or not Lin’s condition is preserved. Then we show that for a positive random variable X and any fixed integer n ≥ 2, the power Xn and the product X1…Xn of n independent copies of X, share the same moment-determinacy property.
