Proof of memoryless property
Webonly continuous distribution that possesses the unique property of memoryless-ness. Now let’s mathematically prove the memoryless property of the exponential distribution. … In formal statistical terms, a random variable X is said to follow a probability distribution with a memoryless property if for any a and bin {0, 1, 2, …} it’s true that: Pr(X > a + b X ≥ a) = Pr(X > b) For example, suppose we have some probability distribution with a memoryless property and we let X be the … See more Consider the following examples: Not Memoryless It is known that a certain brand of laptops last about 6 years, on average, before they die.

Suppose X is a continuous random variable whose values lie in the non-negative real numbers [0, ∞). The probability distribution of X is memoryless precisely if for any non-negative real numbers t and s, we have This is similar to the discrete version, except that s and t are constrained only to be non-negative real numbers instead of integers. Rather than counting trials until the first "success", for example… WebFrom the point of view of waiting time until arrival of a customer, the memoryless property means that it does not matter how long you have waited so far.

WebTheorem The exponential distribution has the memoryless (forgetfulness) property. Proof A variable X with positive support is memoryless if for all t > 0 and s > 0 P(X > s+t X > t) = P(X > s) or, using the definition of conditional probability, P(X > s+t) = P(X > s)P(X > t). An exponential random variable with population mean α has survivor ... Webmemoryless property doesn’t make much sense without that assumption.) It is easy to prove that if the range of X is [0,∞), then X must be exponential. Similarly, if the range of X …
