WebDisadvantages of poisson regression. Mean equals variance. One of the main disadvantages of the poisson regression model compared to other count-based regression models is that the poisson model makes the assumption that the mean of your distribution is equal to the variance. This assumption holds true in many cases where you are … WebWe know that for a Poisson distribution the mean and variance are equal. Therefore . View the full answer. Step 2/2. Final answer. Transcribed image text: The random variable Y has the Poisson distribution with a mean of 50. (a) What is the variance of Y? Answer: (b) Compute the probability, P (Y > 60). Select the closest answer.

Web24.4 - Mean and Variance of Sample Mean. We'll finally accomplish what we set out to do in this lesson, namely to determine the theoretical mean and variance of the continuous random variable X ¯. In doing so, we'll discover the major implications of the theorem that we learned on the previous page. Let X 1, X 2, …, X n be a random sample of ... WebDec 1, 2015 · $\begingroup$ @BCLC Perhaps I misread "Poisson law", but $0$ is in the support of every Poisson-distributed random variable and has positive probability, as I showed. Perhaps not for a "Poisson process", but I would assume that followed an "exponential law". $\endgroup$ dragon essay writer
