Protected Management Frames (PMF) is a standard defined by WiFi Alliance to enhance WiFi connection safety. It provides unicast and multicast management actions and frames a secure method with WPA2/WPA3, which can improve packet privacy protection....
It’s a really simple concept, but it’s difficult to achieve in practice—and a large part of the difficulty comes in being able to truly understand your current and potential customers so you can accuratelyaddress their needs. Getting there is a process that involves a lot of research and...
If x, y, z are IID uniformly distributed on [0, 1], what is the probability that x + y > z? Let X be a uniform (0, 1) random variables, and Y = e^{-X}. a. Find the CDF of Y. b. Find the PDF of Y. c. Find EY. ...
‘must-have’. But more often than not, product/market fit is less about hypothetical numbers and percentages, and more about anin-depth and tangible understanding of who your customers are, and how they feel about you and your product. Is it creating organic growth, where people spread the...
And theMVP. We’ll also see a third element which has become critical even before an MVP can be developed: the problem/market fit. In other words, where the lean methodology is the “How,” the MVP becomes the “What” and the problem/market fit becomes the “Why.” ...
cdfLinear densitypdfpmfProbability densityRescalingHow accurately can final-year students majoring in statistics, physics, and finance label the vertical axis of a normal distribution, explain their label, identify units, and answer a question about the impact of horizontal-axis rescaling? Our survey ...
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. ...
So then, what is the objective definition of product-market fit? For B2B founders, here is the five-part objective definition of product-market fit: You have a narrowly defined customer type and use case; You have acquired ~3-5 satisfied customers who fit that customer type and use case ...
概率质量函数 (probability mass function,PMF)是离散随机变量在各特定取值上的概率。 概率密度函数(p robability density function,PDF )是对 连续随机变量 定义的,本身不是概率,只有对连续随机变量的取值进行积分后才是概率。 累积分布函数(cumulative distribution function,CDF) 能完整描述一个实数随机变量X的概率...
