A brief about me:-

I was an international student in the US, I studied abroad for six years and then worked there for a half a year after graduation,

I graduated with a bachelor’s degree in business administration concentrated in finance, took multiple different business courses throughout my time as a student, and I also worked as an international student assistant at the university. I volunteered and was member of the finance club at the university, and was member of the soccer club.

After graduation, I worked there as credit analyst in a loan company (financial service) for a while then returned back from abroad.

I currently work as an internal auditor in a bank.

Now, I am trying to pursue a master degree abroad in Europe and have a new beginning in different region, and interact with people from different various background. I’ve chosen a master in business analytics because I want to go into more the technical side of business. Information Systems
Data Science and Business Intelligence.

So, these questions are for the admission to the school i am applying for and hoping to get accepted.

I am fully occupied with work and personal things, I am hoping to find a good communicator and writer who can help.

Please let me know if you have any questions..

Here are the admission questions, I need at least one page for each.

Bank Card Payments: Research Proposal, Designing Structure Equation Model

Dear Writers,

I would like to write my thesis (MSc in Finance) about “Bank card or mobile technology: which is the future of payment?”. (Revolut, Bank wallets, AliPay, WeChat Pay, fintech solutions, wallet payment; global/European trends, overview etc.)

BUT:
It is obligatory for the thesis to contain some kind of “serious” mathematical analysis, also.

Before the university accepts my thesis topic, I have to present a short summary, containing what I plan to research in my thesis.

********************************************************
So what I am looking for now is: to Design Research Proposal, find out the Model I need to do empirical study by data or Questionnaire; design Structure Equation Model and some key variables, data. Financial institutions, actors of the market, national banks and statistical offices, World Bank… so there are enermous amount of information, data, statistics available about this topic. On the other hand, it would be nice to have some Chinese connection, because WeChat Pay, AliPay are so popular in China, but in Europe we still do not have these widespread solutions (but this Chinese linkage is not compulsory).
********************************************************

My professor recommended me to read academic papers, such as the paper attached, if I want to choose fintech topic.

If you have more questions, or these short guide was not enough, please contact me to avoid misunderstanding.

I also have second and third thesis topic opportunities, but this fintech topic would be my favourite.

All companies keep databases of its customers. This assignment will be based on a financial credit providing company that has a database of information provided by its customers when they use their credit amounts. These customer records include information on the customers age, employment, other available credits etc. as shown in the database German credit. 

The company is interested in using these variables to predict credit loans for these applicants. The data set contains relevant information for 1,000 customers. This has been outsourced to a business analytics company. It will be your job as the analyst to develop a regression model to predict credit limits for new applicants.

The data are provided in the German credit Excel file 2 sheets:
1.    The Data;
2.    The Codelist with the data description.

As part of that business analytics team you are expected to produce a managerial report to answer the following questions:

1.    What type of variables are Duration and Credit History?

2.    Use methods of descriptive statistics to summarise the numerical variables. Provide an explanation of your findings.

3.    Produce a pivot table and bar chart for Employment comparing Credit Amount. Provide an explanation of your findings.

4.    Produce a pivot table and histogram for Age variable. Provide an explanation of your findings.

5.    Produce a pivot table and line graph showing the Credit Amount related to Age. Provide an explanation of your findings.

6.    Produce a correlation table for all numerical variables. Which variables do you think would have an impact on the provided Credit Amount? Provide an explanation of your findings.

7.    Add a dummy variable (REdummy) for the Real Estate variable and a dummy variable (ORdummy) for whether a customer owns residence. Use 1 for the Yes value and 0 for the No value. Please provide a picture of your data in the appendices to prove this has been completed.

8.    Develop a multiple regression model using Credit Amount as the dependent variable and Duration, Age, Number of credits and Number of dependents as independent variables. Discuss your findings.

9.    Now develop a multiple regression model using Credit Amount as the dependent variable and, REdummy and ORdummy as independent variables. Discuss your findings comparing these to the previous regression in question 8.

10.    Based on your analysis what conclusions and recommendations can you provide for the credit company?

a.    Is there another regression model that could be developed? Discuss?
b.    Are there any variables included that have no impact on predicting annual charges?

The managerial report should contain
    Abstract this should be brief no more than 100 words and answer the following question

The Hepatitis. arff Data set contains information about patients affected by Hepatitis. The task is to generate a classification model to predict Hepatitis histology: Yes/No.

Submit a report based on the answers for the following questions:

a)    Select a suitable decision tree model for predicting Histology.
–    Which model evaluation method did you use (CW, H-O)? Provide an overview of this model, why was it preferred? 
–    Interpret the classification outputs: the tree topology, the accuracy rates.   

b)    Provide a detailed description of the classification model:
–    The tree induction algorithm
–    The attributes selection criteria.
–    The pruning method

c)    Vary the model parameters and discuss the impact on the classification results:
–    Set the REP parameter (Reduced Error Pruning) to TRUE. Explain this tree pruning method. What impact has it made on the outputs, why?
–    Set the parameter unpruned to TRUE, Report and explain any change in the accuracy of results and in the tree structure.
–    Change the confidence factor to 15%, report the impact on the classification outputs, explaining the causes of change.

d)    Visualise the tree and Generate a set of rules along the subtree path: Varices – Ascites Spiders Bilirubin Sex Class No. If you were to generate association rules from the tree how could you reduce the number of rules (hint: speculate about Support and Confidence)?

e)    Perform predictions using two other classification models of your choice: e.g. ANN, SVM, Ensemble learner. Report on the accuracy metrics, discuss the superiority/inferiority of these models performance compared to the decision tree.

f)    Create ROC and Lift charts and interpret them.
