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.

Answer:

the rate of change is 4.

Step-by-step explanation:

It is 4 because to find the rate of change you need to see how many pieces of corn (y) there are for every serving (x). If you see if you plug in the number three in between 2 and 4 for the servings and you follow the pattern of the table you will get 12. Then you subtract 8 from 12 and you get 4.

so basically the rate of change is the difference in corn for every serving.

254.16inches

Step-by-step explanation:

Using sine rule

g/sin25=510/sin122

Sin25=0.4226

Sin122=0.8480

g/0.4226=510/0.8480

Cross multiply

0.8480g=0.4226 x 510

0.8480g=215.526

Divide both sides by 0.8480

g=215.526/0.8480

g=254.16

The length of g is 70 inches.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given,

ΔGHI, h = 13 inches, i = 77 inches and ∠G=170°.

We need to find the length of G

Cosine rule: (for all triangles)

c²=a²+b²-2abcos(C)

=13²+77²-2.13.77.cos(175)

=169+5929-2002cos(175)

=6098-2002(0.598)

=6098-1197.2

c²=4901

Take square root on both sides

c=70.01

G=70.01

Hence, the length of g is 70 inches.

Answer:

x = -5

Step-by-step explanation:

First distribute the 5 on the right side of the equation.

10x - 35 = 15x - 10

Then subtract 10x on each side

-35 = 5x - 10

Then add 10 on each side

-25 = 5x

Divide 5 on each side to get x

-25 / 5 = -5

Answer:

radius=9cm

diameter=18cm

Step-by-step explanation:

Answer:

Radius = 9cm

Diameter = 18cm

Step-by-step explanation:

Remember that the diameter of a circle is the distance between two opposite sides (crossing the middle), and the radius is half of that - the distance from the middle to the outside.

the image shows that the diameter is 18cm, so we know that the radius is 18cm/2, which equals  9cm.

Answer:

11r + 2

Step-by-step explanation:

I combined liked terms which are the r's, then left the 2 alone because you cant combine it with any other number.

Circumference = Perimeter

Perimeter of Circle

= 14π

Also,

Perimeter of Circle

= 2πr

Now,

2πr = 14π

r = 14π/2π

r = 14/2

r = 7cm

The circumference of a circle is 14pi cm. Hence, the radius of the circle will be 7 cm.

Supposing that a considered circle has its radius of 'r' units.

Then, its circumference is given as:

[tex]Circumference = 2\pi r \: \rm units[/tex]

The radius of a circle is half of its diameter.

The circumference of a circle is 14pi cm.

Circumference = Perimeter

Circumference of Circle = 14π

Also,

Circumference of Circle = 2πr

Now,

2πr = 14π

r = 14π/2π

r = 14/2

r = 7cm

Hence, the radius of the circle will be 7 cm.

Answer:

After 20 weeks both tanks have the same amount of fuel.

Diesel tank= 110 gallons

Gasoline tank= 110 gallons

Step-by-step explanation:

Giving the following information:

Diesel tank:

Total capacity= 210 gallons

Unitary daily use= 5 gallons

Gasoline tank:

Total capacity= 430 gallons

Unitary daily use= 16 gallons

First, we structure the total fuel loss formula for each tank:

Diesel tank= 210 - 5*x

Gasoline tank= 430 - 16*x

x= number of weeks

Now, we equal both formulas and isolate x:

210 - 5x = 430 - 16x

11x = 220

x= 20

After 20 weeks both tanks have the same amount of fuel.

Prove:

Diesel tank= 210 - 5*20= 110 gallons

Gasoline tank= 430 - 16*20= 110 gallons
