Let X_1, X_2, ..., X_10 be a random sample of size n = 10 from an exponential distribution with mean 2, X_i \sim EXP(2). a. Find the MGF of the sum Y = \sum_{i= 1}^{10} X_i. b. Wha...
Let X_1, X_n be a sample from a exponential distribution with parameter (1/\theta). The pdf of this distribution is f(x|\theta) = 1/\theta \exp(-1/\theta x) I_{[0, \infty)}(x). Let Y_1, Y_n be the or X and Y are independent exponential random v...
MMO/MGF can sample the magnetic field at a rate of up to 128 Hz. The resulting comparatively high time resolution of the magnetic field measurements, i.e., down to 8 ms, will be necessary when studying the dynamics of and processes within the Hermean magnetosphere, since the Mariner 10 ...
The mean st ress decreases linearly wit h t he increase of t he film t hickness. When film t hickness is over 1 200 nm , t he mean st ress and t he st ress difference wit hin t he selected area are tending towards to steady respectively. Key words : magnesium fl...
1) Mean Generating Function(MGF) 均值生成函数1. A BP neural network multi-step prediction model with the Mean Generating Function(MGF) prolongation matrix of the reconstruction series as the input factor,and the original sample series as the output factor has been formulated. 采用奇异谱分析(...
a sintered body comprises a fluoride of at least one kind of alkaline earth metals selected from the group of Mg, Ca, Sr and Ba, in which the total amount of metallic elements other than the alkaline earth metals is 100 ppm or less on a metal basis, the mean particle diameter of cryst...
