I graduated in economics in 2016. Next year I began studying for my master's degree application exam. My objective was to learn statistics and finance. So I was accepted and started my master's degree in 2018. Unfortunately, the institution I picked did not have a focus on statistics and finance. During my last semester, my frustration and problems with my advisor left me somewhat unmotived to finish my dissertation. So I went my master's degree. Since my graduation days, I have studied coding. I always thought that having the ability to gather, process, and analyze large amounts of data would be valuable in today's world. My first coding experience was with MATLAB and C/C#. MATLAB, my brother used to work with it, and I used to fiddle around to learn how to code ( did nothing special ). C/C#, I did a two-week tutorial I found online. Although I never used these two program languages later, they helped teach me some concepts in programming. While in my graduation, I started using the program languages R and Python. R I used due to its extensive statistical packages support, and the second to its more general usability. During My master's degree, I found myself doing some paid R coding. Usually, it was simple data inference, like running some simple code to find the best linear regression model with variable permutation. Furthermore, I did have some coding experience with Python in helping some research groups in reading SQL databases and scraping online data. After I exited my master's degree, early 2020, I did freelance coding data analysis ( ex.: Inflation prediction models ), machine learning ( ex.: House prediction models in Rio de Janeiro ), and data scraping. I have a Github page with examples github.com/marcoaurelioguerrap ( Although still in Portuguese, my native language. ). If you need statistical models for prediction, inference, or data to be scraped, or organized I might be helpful. Other knowledge I have are Risk Management ( VaR, ES calculations ), stock and options market backtesting, options price models ( BS, Monte Carlo, and SABR ), test for forecast Bias, regressions ( OLS, Logit, probit, Tobit, panel data, time series, GMM, ARIMA, GARCH ). less

*** Please note, I get a fair number of invitations to interview for jobs where the budget is very low, $50 or $25 and so on. While I would like to help, I just don't have the time for smaller or low-budget projects. I am looking for larger, multi-hour projects that are paid on an hourly basis (not flat fee) and have a minimum budget of $500. Thanks for understanding. *** I have over 30 years of experience in research, evaluation, statistics, and project management. I have advanced evaluation and statistical analytic skills and am fluent in Stata and SPSS and have been developing my analytic skills using R to where I am now comfortable working in this language as well.. I also use Mplus for latent variable modeling. I have designed and analyzed online surveys using Survey Monkey, Qualtrix, and REDCap. I have a PhD in clinical psychology and am a tenured Full Professor. I teach beginning and intermediate statistics to doctoral and master's level students. I also teach program evaluation and mental health policy, including substance abuse policy. For samples of my writing style, you are welcome to use the "Look Inside" feature on Amazon to review sections of my book: Substance abuse in America: A documentary and reference guide. I am also happy to provide samples of papers published in peer-reviewed journals. My writing and oral skills are excellent and I am comfortable both developing as well as conducting trainings, workshops, and presentations. I can also help with editing and writing technical or non-technical documents but I am highly selective about this kind of work. I will be happy to review sections in dissertations and theses, but I will not write these or other student papers because I believe this violates academic integrity. I also will not accept homework assignments for the same reason. Things I can help you do: 1) Translate data in Excel or ASCII format into a data set for analysis in just about any commonly used statistical program. 2) Run basic screening and descriptive statistics such as frequencies, measures of central tendency and dispersion, and distributional statistics to assess skew and kurtosis. 3) Run bivariate analyses such as t-tests, correlations, and chi-square tests as well as non-parametric procedures like Kruskal-Wallis. 4) Check missing values and conduct imputation-based analyses for missing data as needed. 5) Run more advanced analytical models including: factorial ANOVA, regression (OLS, binary, ordinal, and multinomial logistic as well as Poisson and negative binomial), GEE for repeated measures data, HLM, factor analysis, latent class analysis, SEM, and growth mixture models. 6) Review and advise on statistical analyses already run including interpretation of the findings. 7) Review, advise, and edit write-ups of statistical results and methods sections. 8) Prospective advice on study design, including sampling, measures, and data collection protocols. 9) Write and edit proposals. I am available to be a project evaluator and would be happy to help you write the evaluation section of your proposal as well as conduct the evaluation if funded. Or, if you just need a review and editing of your proposal, I can do that as well. 10) Develop surveys and survey questions. I have extensive experience developing surveys including online surveys using tools such as Survey Monkey, REDCap, and Qualtrics. If you are unsure whether I can help with your project, please do not hesitate to send me a message. I reply promptly and will give you an honest answer. I never take on work that I don't feel I can complete successfully and within your time frame or which might take me an inordinate amount of time.
