I am Ezra, a data analyst and writer. Any chance I can help you with your analysis as I have handled several dissertations on CSG, and in most cases, I get data from Yahoo Finance. Now that you got your big data already, that makes everything easier. My major is Economics and Statistics, covering a range of courses, including money and banking, Finance, Macro and Micro-economics, research methods and data mining. I am familiar with various research methodologies, including research designs, approaches, philosophies, and data collection and analysis methods. I have handled several quantitative, qualitative, and mixed-studies, both primary and secondary-sourced. I am an expert in many quantitative analysis software, including SPSS, STATA, JAMOVI, R, Refinitiv, PYTHON (Notebooks), JASP, Tableau e.t.c, and qualitative analysis tools such as NVIVO and MAXQDA. I greatly grasp econometrics concepts, including hypothesis testing using inferential statistics such as chi-square, ANOVA, t-tests, correlation, and regressions.
I always keep my work critical, meeting the required standards of high levels of master's and doctoral.
