With over seven years of dedicated experience as a data analyst, I bring a wealth of expertise to the table, ensuring the delivery of top-tier data analytics services. My proficiency extends across a multitude of statistical software packages, including
Stata, Excel, Minitab, IBM SPSS, Gretl, JASP, EViews, Python, and R.
My skills include :
Data Analysis and Statistical Expertise:
-Proficient in statistical analysis, hypothesis testing, and survey analysis, ensuring data-driven decision-making.
-Skilled in performing Analysis of Variance (ANOVA) for robust statistical comparisons.
-Expertise in both qualitative and quantitative analysis techniques to uncover valuable insights.
Data Management and Preprocessing:
-Adept at data cleaning and preprocessing, ensuring the accuracy and reliability of datasets.
-Experienced in transforming raw data into structured, usable information for analysis.
Data Visualization and Interpretation:
-Strong ability to create visually appealing and informative data visualizations.
-Capable of interpreting complex data and conveying meaningful insights to stakeholders.
Programming Proficiency:
-Proficient in Python, R, and SQL, enabling efficient data manipulation and analysis.
- Skilled in automating tasks and creating data-driven solutions through programming.
Data Mining and Pattern Recognition:
-Experienced in data mining techniques to uncover hidden patterns and trends.
- Proficient in pattern recognition and predictive modeling for informed decision-making.
Machine Learning - I'm proficient in both supervised and Unsupervised Machine Learning.
Supervised Learning - Including Support Vector Machine, Logistic Regression, Random Forest,
Decision Tree etc.
Unsupervised Learning - Proficiency in clustering algorithms (e.g., k-means, hierarchical
clustering) and dimensionality reduction techniques (e.g., PCA) for unsupervised learning tasks.
Before building any Machine learning model, I employ the following features to improve accuracy:
-Feature Engineering: I have the ability to select, transform, or create relevant features from raw data to improve the performance of machine learning models.
-Model Evaluation: I have familiarity with metrics like accuracy, precision, recall, F1-score, and area under the ROC curve (AUC-ROC) to evaluate the performance of machine learning models.
-Cross-Validation: I can conduct techniques like k-fold cross-validation to assess a model's performance and generalizability.
-Hyperparameter Tuning: I can optimize model hyperparameters using methods like grid search, random search, or more advanced techniques like Bayesian optimization.
-Overfitting Prevention: I possess techniques such as regularization and dropout to prevent overfitting in machine learning models.
-Ensemble Learning: I can employ ensemble techniques like bagging, boosting, and stacking to combine predictions from multiple models for improved accuracy and robustness.
Time Series Analysis - Univariate Time series - Including Autoregressive Integrated Moving Average
(ARIMA), Moving Average (MA), AutoRegressive (AR), ARCH, SARIMAX,
Seasonal Exponential Smoothing (ETS) Models, Holt-Winters Exponential
Smoothing, Simple Exponential Smoothing etc.
- Multivariate Time Series - Including Vector AutoRegressive and Structural
Vector Autoregression.
