If an impact printer is used multiple simultaneous copies can be printed on multipart forms. Many laser printers can print on both sides of the paper (duplex printing), which is not possible with continuous ...
Conversely, if and are independent random variables and their sum + has a normal distribution, then both and must be normal deviates. [ 46 ] This result is known as Cramér's decomposition theorem , and is equivalent to saying that the convolution of two distributions is normal if and only if both are normal.
Illustration of the Kolmogorov–Smirnov statistic. The red line is a model CDF, the blue line is an empirical CDF, and the black arrow is the KS statistic.. Kolmogorov–Smirnov test (K–S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2), one-dimensional probability distributions that can be used to test whether a sample came from a ...
