What is a randomized estimator? Suppose that X and Y are two random variables whose joint distribution has MGF: Find the covariance between X and Y. Determine the value of c and the covariance and correlation for the joint pmf P(x,y)=c(x+y), x = 1,2, 3 and y = 1,2,3. ...
There exist suchprobability distributionsthat can apply only to countable outcomes. Examples include the number of red cards drawn from a deck or the number of defective items in a batch. For each of such countable outcomes, its probability is calculated through what is known as the PMF by all...
Okay, so a distribution, in this sense, is not even a function, just the probability-assigning rule associated with these various related functions (if discrete: pmf and cdf, if continuous: pdf, cdf). Thanks for your comments, statdad, and for the book recommendation. The Hoel book was ...

“Concerns about response rates have solid theoretical grounding. You can’t make inferences about a larger group if people in the group won’t talk to you. Most of our statistics and margins of error assume having information from every member of a random sample. ...
WhereXis discrete, and pi represents the probability mass function (PMF), the definition will be: WhereXis continuous and f(X) represents theprobability density function(PDF), the definition will look like this: In cases where we’re trying to find the raw moment, we must find the value ...
There are, however, some companies that have managed to not only have a successful launch, but also find a product-market fit (PMF) and subsequently start growing and scaling. In this section, we’re looking at six different examples of inspiring GTM strategies from some interesting and innova...

The increase in the number of malpractice complaints is a burden for both the doctors and the medical system through their impact on the medical practice, as it can lead to the approach to the medical act in a defensive manner, as well as through the judicial procedure which usually lasts ...
