Suppose that whether or not it rains today depends on previous
weather conditions through the last two days. Specifically, suppose
that if it has rained for the past two days, then it will rain
tomorrow with probability 0:7; if it rained today but not
yesterday, then it will rain tomorrow with probability 0:5; if it
rained yesterday but not today, then it will rain tomorrow with
probability 0:4; if it has not rained in the past two days, then it
will
rain tomorrow with probability 0:2. If we let the state at
time n depend only on whether or not it is raining at time n,
Q1：The preceding would then represent a four-state Markov
chain having a transition probability matrix P, and find P,
plz?
Q2：Given that it rained on Monday and Tuesday, what is the
probability that it will rain on Thursday?

Suppose that whether or not it rains today depends on previous
weather conditions through the last two days.
Specifically, suppose that if it has rained for the past two
days, then it will rain tomorrow with probability 0.7; if it
rained
today but not yesterday, then it will rain tomorrow with
probability 0.5; if it rained yesterday but not today, then it

Suppose that the chance of rain tomorrow depends on previous
weather conditions only through whether or not it is raining today
and not on past weather conditions. Suppose also that if it rains
today, then it will rain tomorrow with probability 0.6, and if it
does not rain today, then it will rain tomorrow with probability
0.3, then
a. Calculate the probability that it will rain four days from
today given that it is raining today.
b. What is the...

Find the stationary distribution of this chain
Suppose that the probability it rains today is 0.3 if neither of
the last two days was rainy, but 0.6 if at least one of the last
two days was rainy. Let the weather on day n, Wn, be R for rain, or
S for sun. Wn is not a Markov chain, but the weather for the last
two days Xn = (Wn−1 , Wn ) is a Markov chain with four states...

"consumption depends on income" or whether "income depends on
consumption." Which of the following would be most
relevant?

Problem 1
Whether the stock goes up tomorrow depends upon whether it
increased today and yesterday. If the stock increased today and
yesterday, it will decrease tomorrow with probability α1 . If the
stock increased today and decreased yesterday, it will decrease
tomorrow with probability α2. If the stock decreased today and
increased yesterday, it will decrease tomorrow with probability α3.
Finally, if the stock decreased today and yesterday, it will
decrease tomorrow with probability α4.
a) Define the states...

Suppose today you are considering whether to buy Stock Theta,
and you want to do some basic analysis before buying the shares. By
reading the firm’s most recent Balance Sheet, you find the
following information: Net Income is $5,000,000, Total
Shareholders’ Equity is $25,000,000, Total Assets is $40,000,000.
From other publicly available sources, you further obtain the
following information: the most recent earnings per share (EPS) is
$3, the dividend payout ratio is 60%, and the firm’s beta is 1.4....

110. Suppose that last month one U.S. dollar could be
exchanged for one euro, while, today it takes two U.S. dollars to
buy one euro. From this, we can conclude that:
a. the U.S. dollar has depreciated relative to the
euro.
b. the euro has appreciated relative to the U.S.
dollar.
c. the U.S. dollar has appreciated relative to the
euro.
d. both the U.S. dollar and the euro have depreciated
relative to each other.
e. Both A and B...
