Question
Let X be a discrete random variable. For each of the following cases when
You have to compute the TRUE and EMPIRICAL values for the mean and variance of X. For the true values, you can calculate them manually or you can first generate such a distribution with the specific parameters and then use the functions provided by the MATLAB to compute its mean and variance. For the empirical values, you first randomly generate N samples from such a distribution, and then use the mean and var functions to compute the empirical mean and variance on those samples, respectively. You have to repeat this process for 10 times and obtain the average value of the computed empirical mean and variance over the 10 repeats. Please experimented with
N = [5; 10; 50; 100; 500; 1000; 5000] and then plot a 2D figure, where x-axis denotes N and the y-axis denotes the empirical values for mean or variance. Finally, you have to add a line of the true values for the mean or variance. Please use different colors for the true and empirical values. For each case, you have to submit
1. MATLAB codes, which should be put in script _les (.m);
2. Two figures, which should be in eps format (.eps). One is for the empirical and true mean values and the other is for the empirical and true variance values.
Summary
This question belongs to MATLAB software and discusses about application of MATLAB to probability and statistics and to compute the true and empirical values of mean and variance of a random variable.

Download Full SolutionThings got very difficult during my 3rd semester of my Mechanical Engineering course. After coming to the States I realized that education here is very challenging. Thanks to HelpWithAssignment.com, I completed all the fluid mechanics reports with an A+. Now currently they are working on my mid-tern research report and I am happy with the service.
The online Visual C++ programming assignment expert assigned to me by HwA for the assignment help request that I had submitted actually stuck to all the criteria that was to be met for the assignment. He was available at all times of the day in case I needed to discuss any additional points that may have been discussed in class.
I had no clue about how to write a qualitative research paper on Faulkner and so I approached HelpwithAssignment.com. I was also not sure whether they could help me or not but to my surprise they started asking the right kind of questions to me. When I clarified them with my professor, she was impressed and told me that I understood the concept of a research paper. The rest of it was a walk in the park. With my professorâ€™s inputs they provided an excellent research paper and help me get an A
I was having problem completing my economics assignment submission on the concept of demand and supply for my mid terms. That is when one of my friends suggested HelpwithAssignment.com and they got back to me as soon as I contacted them. I was very impressed by their expert econ tutors and they have been my guides since that time. The professors are happy with the crisp and relevant assignment work and I am happy with their indepth understanding and research for each assignment and timely delivery of assignments. Thank you HelpwithAssignment.!!!
The reference material and notes provided by the online electrical engineering tutor assigned to me by HwA was exactly what I was looking for. Keeping up with the course load is difficult enough without having to run from pillar to post searching for research material. The online electrical engineering tutor at HwA made my work much easier by providing me high quality reference material which met the specifications given by my professor.

this is a very good website
I have 50 questions for the same test your page is showing only 28
hi can you please help or guide me to answer my assignments. thanks
hi can anyone help or guide me to my assignments. thanks
This solution is perfect ...thanks
Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
