Über diesen Service
ChatGPT can write you a regression script in seconds. What it can't do is tell you whether that test was the right one to run, whether your data meets its assumptions, or what the result means for your question. Most freelancers just copy that AI code and hand it back unchecked I don't.
I run every analysis by hand: choosing the right test, checking assumptions, and interpreting results in plain language you can defend.
WHAT I CAN DO:
- Data cleaning and preprocessing
- Descriptive statistics and EDA
- Hypothesis testing (t-tests, ANOVA, chi-square)
- Regression analysis (linear, logistic, multiple)
- Correlation, clustering, time-series analysis
- Large-scale processing with PySpark/Dask
- Visualization (matplotlib, seaborn, ggplot2)
- Plain-language interpretation, not raw output
TOOLS: Python (pandas, SciPy, statsmodels, scikit-learn), R/RStudio (tidyverse), PySpark for large datasets
WHO THIS IS FOR:
- Students needing analysis for a thesis or coursework
- Researchers analyzing survey or experimental data
- Businesses needing insight from large datasets
WHY WORK WITH ME:
- STEM background, published research experience
- Every test choice and result explained
- Revisions until you're satisfied

FAQ
Do you work with both Python and R, or do I need to choose?
Both are included — I'll use whichever tool fits your dataset and analysis best.
Do you handle true big data (millions of rows)?
Yes, for very large datasets I use PySpark/Dask for efficient processing alongside standard statistical methods.
Will I get the code as well as the results?
Yes, you'll receive the full Python/R scripts along with a written explanation of the results.
Can you help me choose which statistical test to use?
Yes, if you're unsure which test fits your data and research question, I'll recommend and justify the right approach.
Do you provide visualizations along with the analysis?
Yes, clear charts and graphs are included to support the statistical findings.
