Marketing variables that are included in consumer discrete choice models are often endogenous. Extant treatments using likelihood-based estimators impose parametric distributional assumptions, such as normality, on the source of endogeneity. These assumptions are restrictive because mis specified distributions have an impact on parameter estimates and associated elasticities. The normality assumption for endogeneity can be inconsistent with some marginal cost specifications given a price-setting process, although they are consistent with other specifications. In this paper, we propose a heterogeneous Bayesian semiparametric approach for modeling choice endogeneity that offers a flexible and robust alternative to parametric methods. Specifically, we construct centered Dirichlet process mixtures (CDPM) to allow uncertainty over the distribution of endogeneity errors. In a similar vein, we also model consumer preference heterogeneity nonparametrically via a CDPM. Results on simulated data show that incorrect distributional assumptions can lead to poor recovery of model parameters and price elasticities, whereas the proposed semiparametric model is able to robustly recover the true parameters in an efficient fashion. In addition, the CDPM offers the benefits of automatically inferring the number of mixture components that are appropriate for a given data set and is able to reconstruct the shape of the underlying distributions for endogeneity and heterogeneity errors. We apply our approach to two scanner panel data sets. Model comparison statistics indicate the superiority of the semiparametric specification and the results show that parameter and elasticity estimates are sensitive to the choice of distributional forms. The CDPM specification yields evidence of multimodality, skewness, and outlying observations in these real data sets.

The table representing the linear function is attached below.
A linear function is defined as the relation between two variables . A linear function represents a straight line on the number plane.
A linear function is of the form y = mx + c , where m is the slope of the function and c is the y-intercept of the function.The slope is defined as the tangent of the angle made by the line with the positive x-axis.The y-intercept is the point of intersection of the line and the y-axis.Given the slope of the function as 5 and the y-intercept as 20 .
So m = 5 and c = 20
Therefore the linear function is of the form : y=mx + c
Substituting the values we get: y = 5x + 20
Now
at x=0 , y = (5 ×0) + 20 = 20
at x=-4 , y = (5 × -4) + 20 = 0
at x= 4, y = (5 × 4) + 20 = 40
at x= 8, y = (5 × 8) + 20 = 60
Therefore the table for the linear equation is attached.

a school class went on a field trip to see a magician perform. there were 17 females and 20 males in the class. the magician randomly selected a volunteer from the audience, which had 52 females and 68 males. given that the randomly selected audience member is a student from the class, which equation can be used to find the probability, p, that the person is also a female?
An equation that can be used to find the probability, p, that the person is also a female given that the randomly selected audience member is a student from the class is: P = (17/120) ÷ (37/120)
For given question,
The audience of the magic show is conformed by a total of 120 people, 52 of which are female and 68 are men.
Within the audience there is a school class of 37, of these students, 17 are female and 20 are male.
First we find the probability of selecting a student from the class in all audiences.
P(A) = 37/120
Now, the probability that the selected student is female student:
P(B) = 17/120
We need to write an equation for combined probability which is given by,
P = (17/120) ÷ (37/120)
Therefore, an equation that can be used to find the probability, p, that the person is also a female given that the randomly selected audience member is a student from the class is: P = (17/120) ÷ (37/120)

If a cantaloupe that weighs 3.0 pounds costs $3.87, approximately how much will a 2.22 pound cantaloupe cost?
Answer:[tex]1.29 * 2.22 = 2.86[/tex]
$2.86
Step-by-step explanation:
First we need to find the price per pound for the cantaloupe
[tex]3.87/3.0=1.29[/tex]
So one pound of cantaloupe costs $1.29
Now multiply the price per pound by the weight of the second cantaloupe
[tex]1.29*2.22=2.86[/tex]
So the price for a cantaloupe that weighs 2.22 lbs would be $2.86

Can someone help me solve this question? | x-9 | +7 = 8
Answer:
x = 8
x = 10
Step-by-step explanation:
lx -9l + 7 = 8
lx - 9l + 7 - 7 = 8 - 7
lx - 9l = 1
Split into a positive and a negative case.
x - 9 = 1 and - (x - 9) = 1
Add nine to both sides
x - 9 + 9 = 1 + 9
x = 10
- (x - 9) = 1
Subtract 9 from both sides
- 8 = - x
Multiply both sides by negative 1
x = 8

Find the circumference and area of the figure if each unit on the graph measures 1 centimeter. Round answers to the nearest tenth, if
necessary.
The area and circumference of a circle is 40.8cm² and 22.6 cm respectively
Circumference of a circleThe formula for calculating the circumference of a circle is expressed as:
C = 2πr
where
r is the distance between A and B
AB = r = √(5-2)²+(3-1)²
r = √9 + 4
r = √13
r = 3.605
Determine the circumference
C = 2(3.14)(3.605)
C = 22.6394
Hence the circumference of the circle is 22.6 cm
Determine the area
Area = πr²
Area = 3.14 * 3.605 * 3.605
Area = 40.8cm²
Hence the area and circumference of a circle is 40.8cm² and 22.6 cm respectively

£440
Answer:
£440
Step-by-step explanation:
According to the question,
Daniel invests £2200 into his bank account and he receive 10% per year simple interest.
So, money he'll have after a year = 10% of 2200 = 220
Money he will have after two years = 220×2 = 440
So he will have £440 after two years
