Sobre este Serviço
**Turn raw data into scientific insights or business-driven solutions.**
Struggling with messy datasets, statistical models, or presentation visuals? I deliver clean, reproducible, and fully documented data analysis using **R** and **Python**.
### What I Offer:
**Data Cleaning & Wrangling:** Restructuring messy data, handling missing values, and ETL pipelines (Pandas, Tidyverse).
**Exploratory Data Analysis:** Summary statistics, trends, distributions, and correlation matrices.
**Statistical Analysis:** Hypothesis testing (t-tests, ANOVA, Chi-Square), regression modeling (Linear, Logistic, Mixed-Effects), PCA.
**Data Visualization:** High-res static plots (`ggplot2`, `Seaborn`) and dynamic dashboards (`R Shiny`, `Plotly`) formatted for APA/IEEE or corporate decks.
**Machine Learning:** Classification, clustering, time-series forecasting, and model evaluation (`scikit-learn`).
**Reproducible Reports:** Dynamic knitted output via R Markdown, Quarto, or Jupyter Notebooks (PDF/HTML/Word).
*Includes commented source code (`.R`, `.py`, `.ipynb`) and strict data privacy.*
**Note:** Please message me with your dataset details before ordering!

Perguntas frequentes
Will I get the original source code along with the results?
Yes, absolutely. Every package includes fully documented, readable source code (R scripts, R Markdown, Python scripts, or Jupyter Notebooks) so you can verify, reproduce, or build upon the analysis later.
Can you do my "Homework"?
No. The only help I can offer you for this kind of tasks is Tutoring and Support. Any kind of cheating is forbidden within this platform.
Do you handle custom orders if my project doesn't fit the package tiers?
Yes! Many scientific and business projects require unique approaches. Send me a brief message detailing your goals and dataset, and I will generate a tailored Custom Offer specifically for your project scope.
Can you format statistical charts for specific academic journal requirements?
Yes. I can customize figure dimensions, resolution (300+ DPI), color profiles (RGB/CMYK), and formatting styles to adhere strictly to guidelines from publishers like IEEE, Nature, Elsevier, APA, or custom brand style guides.
How do you handle dataset privacy and confidentiality?
Your data security is paramount. I never share, publish, or re-use client datasets. If required, I am happy to sign a Non-Disclosure Agreement (NDA) before you send the files over.
What file formats can I submit my data in?
I accept almost any data format, including CSV, Excel (.xlsx), JSON, SQL database exports, SPSS (.sav), Stata (.dta), SAS, or native RData files.
What if my data needs extensive cleaning before analysis can begin?
Basic data cleaning is included in all packages. However, if your data requires deep manual restructuring, OCR from scanned documents, or extensive web scraping, we can easily add a data preparation extra to the order.
