Let’s switch gears and move away from continuous data. Suppose we take another random sample of our product from each of the production lines. However, instead of measuring a characteristic, inspectors evaluate each product and either accept or reject it. Binary data can have only two values. If you can place an … See more Continuous data can take on any numeric value, and it can be meaningfully divided into smaller increments, including fractional and decimal values. There are an infinite number of possible values between any two … See more Count data can have only non-negative integers (e.g., 0, 1, 2, etc.). In statistics, we often model count data using the Poisson distribution. … See more Web1 day ago · We consider a binary hypothesis testing problem in the Bayesian framework with a priori probabilities of the hypotheses H 0 and H 1 denoted by π 0 and π 1 = 1 − π 0, respectively. Under hypothesis H i , the transmitter sends the signal s i ∈ R k , which passes through a linear channel and is corrupted by Gaussian noise.
