Moment Generating Function of Exponential Distribution

WebbThe moment-generating function (mgf) of a random variable X is given by MX(t) = E[etX], for t ∈ R.

WebbOnce we establish part (b), the proof of part (a) is easy: if X and Y are bounded, then their mgf’s exist for all t and thus their cdf’s are the same iff their moments are the same for any order. The condition that the mgf exists in a neighborhood of 0 is important. There are random variables with finite moments of any order, but their WebbLas mejores ofertas para Consola ligera Nintendo Gameboy L9291 dorada GB Japón están en eBay Compara precios y características de productos nuevos y usados Muchos artículos con envío gratis!

WebbThat result is clear as independence implies M X, Y ( s, t) = E ( e s X + t Y) = E ( e s X) E ( e t Y). Since the MGFs of the marginals are determined by the joint MGF we have: X, Y independent M X, Y ( s, t) = M X, Y ( s, 0) ⋅ M X, Y ( 0, t) But after searching online I found only a fleeting reference, without proof, to the converse.

WebbYou can use independence of X and Y (notice that that is independence with respect to both the variables) to say that E[XY] = E[X]E[Y]. But it doesn't make sense to say that X is "independent" because the natural next question would be "independent of what?". Webbas this moment generating function determine the joint distribution so from this we can have X+Y and X-Y are independent random variables. 2. Consider for the experiment …
