Nettet22. jul. 2024 · While the first statistic X 1 + 2 X 2 + X 3 in the linked post is definitely not sufficient for θ as shown in detail in this thread, the second statistic 2 X 1 + 3 X 2 + 4 X 3 is sufficient for θ by my calculations. Suppose H ( X 1, X 2, X 3) = 2 X 1 + 3 X 2 + 4 X 3 and T ( X 1, X 2, X 3) = X 1 + X 2 + X 3. NettetThis paper is concerned with the distributed and centralized fusion filtering problems in sensor networked systems with random one-step delays in transmissions. The delays are described by Bernoulli variables correlated at consecutive sampling times, with different characteristics at each sensor. The measured outputs are subject to uncertainties …

Nettet28. jun. 2024 · Also, note that if X X and Y Y are random variables, then a linear combination of the random variables is given by: Y = aX+bY Y = a X + b Y Where a a and b b are constants so that: E(Y) = aX+bY = aE(X)+ bE(Y) E ( Y) = a X + b Y = a E ( X) + b E ( Y) Variance of Linear Combinations of Random Variables NettetMathematically linear combinations can be expressed as shown in the expression below: Y = c 1 X 1 + c 2 X 2 + ⋯ + c p X p = ∑ j = 1 p c j X j = c ′ X. Here what we have is a set of coefficients c 1 through c p that is multiplied bycorresponding variables X 1 through X p. NettetHow do I use linear combinations of normal random variables to find probabilities? If the random variables are normally distributed and independent you might be asked to find probabilities such as. P(X 1 + X 2 + X 3 > 2Y + 5)This could be given in words.
