Linear regression (Ch.10)
The linear regression is a problem of relating the
mean value of a single r.v. Y to a single independent
variable x using a linear relationship.
Suppose we have a realization ( y 1 , y 2 , , y n ) of a
sample Y = cfw_
Lecture # 9
Correlation
Let X and Y be two not necessarily
independent random variables. Their joint
probability distribution function is
F ( x, y ) = P ( X x, Y x ) .
If X and Y are discrete, then the joint
probability distribution (j.p.d.) is
P( X = x,
Lecture #8
Tests for two samples (sec.9.1)
Suppose you would like to compare the mean price of a
home in one state with that in another.
If you have got two independent random samples of
size n 30 (large samples), you may to use the
following.

Hypotheses testing
Let a statistical model be given:
X n = cfw_ X1 , ., X n and F( x, ).
Different hypotheses may be posed about this
model.

Continuous r.v.
Suppose a r.v. X takes values from [0,1] with
equal probabilities. Simple events points of
[0,1] . = [0,1] . contains points.
Let an events A occurs if X = a, 0 a 1.

place required constraints on monetary
policy, to prevent a cruel circle of inflation
and high public expectations of inflation?

Government in the Economy
Nothing arouses as much controversy as
the role of government in the economy.
Government can affect the macroeconomy
through two policy channels: fiscal policy
and monetary policy.
