What problem does it solve?
This Skill removes friction from retrieving, parsing, and analyzing Turkish central bank (TCMB) EVDS time series by handling the EVDS3 path-based API format, date parsing quirks, and common data-quality issues so users can get clean, analysis-ready series quickly.
Core Features & Use Cases
- Direct EVDS access: Fetch single or multiple series via EVDS3 endpoints using an API key provided in request headers.
- Time series processing: Automatic date parsing for daily/weekly/monthly/quarterly/yearly formats, frequency conversion and resampling.
- Analytical toolbox: Descriptive statistics, correlation matrices, OLS regression, ARIMA/SARIMA forecasting, VAR, STL seasonality decomposition, anomaly detection, PCA and interactive Plotly dashboards.
- Practical use case: Compare monthly TÜFE with policy rate and USD/TRY, run stationarity checks, fit ARIMA for forecasting, and export an interactive HTML dashboard plus CSV of results.
Quick Start
Use the skill to fetch TP.FG.J0 (TÜFE) from 01-01-2018 to 31-12-2024 with your API key and return descriptive statistics, an ARIMA forecast for 12 periods, and an interactive Plotly HTML chart.
