EEL6029 Statistical inference课程简介

That sounds like a challenging and exciting course! Here are some key topics that might be covered in such a course:

1. Probability theory: This would include understanding the axioms of probability and basic rules of probability, such as conditional probability and Bayes’ theorem.
2. Statistical inference: This would cover topics such as estimation, hypothesis testing, and confidence intervals. Students would learn about point estimation, maximum likelihood estimation, and Bayesian estimation. They would also learn about hypothesis testing, including null and alternative hypotheses, p-values, and type I and type II errors.

PREREQUISITES 

1. Linear regression: This would involve understanding the basics of simple and multiple linear regression, including the assumptions and limitations of the models. Students would learn about least squares estimation, hypothesis testing, and confidence intervals.
2. Bayesian statistics: This would cover the principles of Bayesian inference, including Bayes’ theorem, prior and posterior distributions, and Bayesian model selection. Students would learn about Markov Chain Monte Carlo (MCMC) methods for sampling from complex posterior distributions.
3. Machine learning: This would include an introduction to basic machine learning techniques such as decision trees, random forests, and support vector machines. Students would learn about the trade-offs between different types of models, as well as methods for model selection and evaluation.
4. Time series analysis: This would involve understanding the basics of time series models, including autoregressive (AR), moving average (MA), and autoregressive integrated moving average (ARIMA) models. Students would learn about forecasting and time series model selection.
5. Cyber systems modeling: This would cover modeling of complex cyber systems using mathematical tools, such as graph theory and network analysis. Students would learn about the basics of cyber security and how to model and analyze cyber attacks using statistical methods.

Overall, this course would provide a strong foundation in mathematical statistics and its applications to complex cyber systems, data analytics, and Bayesian intelligence.

(a) Given that ball $k$ is chosen from the first urn, the probability of choosing three red and two blue balls from the second when sampling with replacement is the binomial probability
$$
P(\text { three red|ball } k)=\left(\begin{array}{l}
5 \
3
\end{array}\right)\left(\frac{k}{10}\right)^3\left(1-\frac{k}{10}\right)^2 .
$$
The probability of choosing ball $k$ from the first urn and three red balls from the second is therefore
$$
\begin{aligned}
P(\text { three red and ball } k) & =P(\text { three red } \mid \text { ball } k) P(\text { ball } k) \
& =\left(\begin{array}{l}
5 \
3
\end{array}\right)\left(\frac{k}{10}\right)^3\left(1-\frac{k}{10}\right)^2 \times \frac{1}{11},
\end{aligned}
$$
and the unconditional probability of choosing three red balls from the second urn is
$$
\begin{aligned}
P(\text { three red }) & =\sum_{k=0}^{10} P(\text { three red and ball } k) \
& =\sum_{k=0}^{10}\left(\begin{array}{l}
5 \
3
\end{array}\right)\left(\frac{k}{10}\right)^3\left(1-\frac{k}{10}\right)^2 \times \frac{1}{11} \
& \approx 0.1515
\end{aligned}
$$
This can be computed in $\mathrm{R}$ as
$$
\begin{aligned}
& >\operatorname{sum}(\operatorname{dbinom}(3,5,(0: 10) / 10) / 11) \
& \text { [1] } 0.1515
\end{aligned}
$$
(b) The conditional probability that the chosen ball from the first urn was numbered $k=6$, given that three red balls were chosen from the second,is
$$
\begin{aligned}
P(\text { ball } k=6 \mid \text { three red }) & =\frac{P(\text { three red and ball } k=6)}{P(\text { three red })} \
& =\frac{\left(\begin{array}{c}
5 \
3
\end{array}\right)\left(\frac{k}{10}\right)^3\left(1-\frac{k}{10}\right)^2 \times \frac{1}{11}}{P(\text { three red })} \
& \approx \frac{0.03142}{0.1515} \approx 0.2074
\end{aligned}
$$

1. (a) One possible approach:
   $$
   \begin{aligned}
   &>\operatorname{sapply}(\operatorname{seq}(0.2,0.9, \text { by }=0.2), \
   &\text { function(p) mean(replicate }(10000, \operatorname{sim} 1(p))))
   \end{aligned}
   $$
   [1] 0.49130 .49650 .50340 .4991
   This suggests that the probability of heads may be 0.5 for any $p$.
   (b) Let $A$ be the event that the process returns a head, and let $B$ be the event that the process ends after the first two flips. Then
   $$
   P(A)=P(A \cap B)+P\left(A \mid B^c\right) P\left(B^c\right)
   $$
   Now $A \cap B$ is the event that the first toss is a tail and the second toss is a head, so $P(A \cap B)=(1-p) p . B$ is the event that either the first toss is a head and the second a tail, or the first is a tail and the second is a head; so $P(B)=2 p(1-p)$ and $P\left(B^c\right)=1-2 p(1-p)$. If the process does not end with the first two tosses then it starts over again independently, so $P\left(A \mid B^c\right)=P(A)$. Therefore $P(A)$ satisfies
   $$
   P(A)=p(1-p)+P(A)(1-2 p(1-p))
   $$
   and thus
   $$
   P(A)=\frac{p(1-p)}{2 p(1-p)}=\frac{1}{2},
   $$
   as the simulation in part (a) suggests. The requirement that $p>0$ and $p<1$ ensures that the denominator is positive and that the process is guaranteed to end.
