Distributionally robust stochastic programs with side information based on trimmings
This is a research paper whose authors are Adrián Esteban-Pérez and Juan M. Morales.
Abstract:
We look at stochastic programmes that are conditional on some covariate information, where the only knowledge of the possible relationship between the unknown parameters and the covariates is a limited data sample of their joint distribution. We build a data-driven Distributionally Robust Optimization (DRO) framework to hedge the decision against the inherent error in the process of inferring conditional information from limited joint data by leveraging the close relationship between the notion of trimmings of a probability measure and the partial mass transportation problem.We demonstrate that our technique is computationally as tractable as the usual (no side information) Wasserstein-metric-based DRO and provides performance guarantees. Furthermore, our DRO framework may be easily applied to data-driven decision-making issues involving tainted samples. Finally, using a single-item newsvendor problem and a portfolio allocation problem with side information, the theoretical findings are presented.Conclusions:
We used the relationship between probability reductions and partial mass transit in this study to give a straightforward, yet powerful and creative technique to expand the usual Wasserstein-metric-based DRO to the situation of conditional stochastic programming. In the process of inferring the conditional probability measure of the random parameters from a limited sample drawn from the genuine joint data-generating distribution, our technique generates judgments that are distributionally resilient to uncertainty. In a series of numerical tests based on the single-item newsvendor issue and a portfolio allocation problem, we proved that our strategy achieves much higher out-of-sample performance than several current options. We backed up these actual findings with theoretical analysis, demonstrating that our strategy had appealing performance guarantees.To learn more about probability, visit :

Find the degree of the term.
Answer:
Here,
-2xy³
The exponent of x = 1
The exponent of y = 3
Thus, the degree of the term = 1+3 = 4
Step-by-step explanation:
Given the term
-2xy³
We know that the degree of the term involving xy expression cab be calculated by adding the exponents of x and y.
In other words, the degree of a term in two variables would be the sum of the exponents of the variables in the termHere,
-2xy³
The exponent of x = 1
The exponent of y = 3
Thus, the degree of the term = 1+3 = 4

The correct options for the linear combinations of the vectors are given by:
A, B, C, D, E and F.
What is a span between two vectors?The span between two vectors is the set that contains all linear combinations between these two vectors.
Supposing we have two vectors u1 and u2, as is the case in this problem, the infinitely many linear combinations have the following format:
k1u1 + k2u2
In which k1 and k2 are real numbers.
With k1 = 4 and k2 = -7, we get that option A is correct.
For option B, the vector 0 will always be a part of the span, as it can be formed with constants 0, hence it is correct.
The dimension of the span is of 3, as the vectors have 3 elements, hence option C is correct.
The underlying vectors will always also be part of the span, as they can be formed with their constant 1 and the others at 0, hence options D and F are correct.
The size of the span of any vectors is of infinity, hence option E is correct while option G is not.

Select the physical components that enable data to travel across a network.

The correct option is (a) connectors. The elements that give data on the network a way to move between nodes. This covers network media, connectors, and network interface cards (NIC).
A message is a piece of data sent over the internet, but before a message is sent, it is divided up into smaller pieces called packets. Using Transport Control Protocol (TCP) and Internet Protocol (IP), these messages and packets move between sources (TCP).
The cables (coaxial, twisted pair, fiber optic, and telephone lines) connecting the various network hardware components, the network adapters used by computers connected to the network (hosts), and any concentrators, repeaters, routers, or bridges employed in the network make up the physical network. The term "physical connection" refers to the total number of trunk lines, complete circuits, and connections—including those made by wire, optics, radio signal, or other means—necessary to provide reasonably adequate telecommunications service among telecommunications providers.

The sequence 0, 10, 18, 25, 33, ... is not an arithmetic sequence. Then the correct option is B.
What is an arithmetic sequence?In a Number-crunching Succession, the distinction between one term and the following is steady. Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
The sequence is given below.
0, 10, 18, 25, 33, ...
The difference between two successive terms is given as,
⇒ 33 - 25
⇒ 8
⇒ 25 - 18
⇒ 7
The common difference is not the same.
Thus, the given sequence is not an arithmetic sequence. Then the correct option is B.

the supermarket displays the unit price for the 24.0-ounce box in terms of cost per ounce, but displays the unit price for the 24-ounce box in terms of cost per pound. what are the unit prices, to the nearest cent, given by the supermarket? unit price for the 15.3-ounce box
So the supermarket unit price for 24.0 ounce box is $0.2 and 15.3-ounce box is $0.3
Step-by-step explanation:
It is common that superstores often display units of their choice. That's okay. What you can do is perform some simple calculations to calculate the unit price in whatever unit you want.
For example, here the price for 15.3 ounce box is $4.62
So, the price for 1 box would be
15.3 x 1/15.3 = 4.62 x 1/15.3
1 box = $0.3 (Unit price)
Similarly,
24 = 5.35
24 x 1/24 = 5.23 x 1/24
1 box = $0.2 (Unit price)

What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to evaluate the given equation?The equation is given as
2n = 2m + n
Subtract n from both sides of the equation
So, we have
-n + 2n = 2m + n - n

What is an Implicit Cost?
Any value that has previously came about however isn't always necessarily proven once more reported as a awesome object is called an implicit price. It stands for a marginal utility that develops whilst a enterprise devotes inner assets to a venture without receiving any direct payment for the usage of such resources.Figuring out implicit costs:
You ought to first decide the prices. you could add up the express expenses you're aware of:you may calculate the accounting earnings through deducting the explicit charges from the sales.To calculate the genuine economic profit, deduct both specific and implicit costs.Implicit cost is the price of a production factor that is owned by the producer. Walter might have made $4 in the 30 minutes it takes to make a birdhouse.
