(Multiple choice, can select more than one)

Under our standard regression assumptions, which of the following is true?

E(u|X,Y) = 0

E(u|X) = 0

E(u) = 0

Answer #1

Under our standard regression assumptions, all of the following are true:

**E(u|X,Y)=0**

**E(u|X)= 0**

**E(u) = 0.**

Let me explain this in brief.

For our estimates of the population parameters to be consistent
in a multivariable regression model, we need which of the following
assumptions to be true?
a)There are no large outliers in X1, X2, …, Xk, or Y.
b)There is no perfect multicollinearity.
c)The variance of the error, u, given every value of every X, is
constant.
d)There is no imperfect multicollinearity.
e)The sample is randomly selected from the population of
interest.
f)The errors, u, are normally distributed. g) E[u |...

Multiple Linear Regression
We consider the misspecification problem in multiple linear
regression. Suppose that the following model is adopted y = X1β1 +
ε while the true model is y = X1β1 + X2β2 + ε. For both models, we
assume E(ε) = 0 and V (ε) = σ^2I. Figure out conditions under which
the least squares estimate we obtained is unbiased.

Which of the following is not true about CAPM? Multiple
Choice
Not all assumptions of CAPM are realistic
CAPM allows for multiple sources of systematic risk
The expected return of a security with a beta of zero is the
risk-free rate
Expected returns increase with higher beta

Using p-value method for testing hypotheses you
reject H0 if the p-value is less

fail to reject H0 if the p-value
is less than or equal to the significance level
support H1 if the p-value is
greater than...

Suppose we wanted to change our requirement that you have had
under discussion in the following way:
In <cond> the same identifier cannot be used more than
once. In other words, the previous modification to would have
allowed the following: [(X>=Y+Z) and (U < X)]
This would have been allowed because although X appears twice in
the <cond> it only appears once in each <comp> that
makes up the <cond>. Under our new requirement above, this
<cond> would not be...

Multiple choice: Which one of the following statements is
true?
(a) There is still no direct evidence that a comet or asteroid
impact helped cause the Cretaceous–Paleogene (i.e.,
Cretaceous-Tertiary) extinction during which the dinosaurs perished
because no matching crater has yet been found.
(b) The collision of Comet Shoemaker-Levy 9 with Jupiter
dramatically illustrated the amount of energy that can be released
when an asteroid or comet hits a planet.
(c) In principle, nothing can be done to prevent collisions...

In simple linear regression analysis which of the following
assumptions must be met in order to ensure valid conclusions?
* The variances for each X are independent of each other.
* the variance of X is equal to the variance of Y
* All of these statements are true.
* The X variable and the Y variable each have histograms that
are normal
* X is linearly related to Y
