Answer:
Only the first autocovariance function : γ(t,r) is covariance stationary, the remaining are not covariance stationary
Explanation:
For a process to be covariance stationary/ weak stationary/ second order stationary it must satisfy these two conditions below:
In order words, {Xt} is said to be (weakly) stationary if :
1. it is independent of t, and
2. For each h, x(t + ћ, t) is independent of t.
In that case, we write:
γX (h) = γX (h,0⇒)
Hence only the first autocovariance function : γ(t,r) is covariance stationary since Autocorrelation function (ACF) is time independent.
The remaining are not covariance stationary because ACF is time dependent.
Answer:
The correct answer is letter "A": full screen.
Explanation:
The full screen is a scoring model carried out to determine the feasibility of a product. In this stage, the technical and commercial aspects of that product are evaluated to find out if it is possible to be materialized or if the development of that good should stop.
Answer:
The statement is: False.
Explanation:
Net Income <em>is the result of subtracting a company's expenses in generating income from the total revenue and deducting taxes from that figure</em>. The net income may be distributed as a dividend among common stock shareholders or retained by the company. Instead, capital refers to financial resources such as equity, debt, trading, and working capital.
Answer:
"Job Shop" would be the appropriate solution.
Explanation:
- A workshop seems to be a small enterprise or organization that makes unique items within one person at the same time. It is a production unit that deals in tailor-made including custom-built components in limited amounts.
- Under that same production or manufacturing economy, a large number of products are manufactured with smaller quantities requiring a remarkable setup as well as production measures.
