A First Analysis in R

Move from a business question to an auditable result with objects, functions, inspection, and clear interpretation.

باز کردن

Vectors, Types, and Subsetting

Understand atomic vectors, coercion, vectorized operations, missing values, and safe subsetting.

45 min4 هدف

باز کردن

Data Frames, Factors, and Dates

Build rectangular data, encode categories, parse dates, and validate keys before joins.

45 min4 هدف

باز کردن

Functions, Pipes, and Project Workflow

Turn repeated calculations into validated functions and portable, reproducible workflows.

45 min4 هدف

باز کردن

Importing, Cleaning, and Validating Data

Treat cleaning as an auditable chain of schema, type, missingness, range, and key checks.

45 min4 هدف

باز کردن

Transforming Data with dplyr

Use a small grammar of verbs for readable row, column, grouping, and join operations.

45 min4 هدف

باز کردن

Exploratory Data Analysis

Describe centre, spread, shape, relationships, and unusual observations without turning discovery into confirmation.

45 min4 هدف

باز کردن

Data Visualization with ggplot2

Use layers, scales, facets, labels, and accessible encodings to make defensible statistical graphics.

45 min4 هدف

باز کردن

Statistical Foundations and Linear Regression

Connect estimands, uncertainty, intervals, tests, regression, diagnostics, and causal restraint.

45 min4 هدف

باز کردن

Time-Series Objects, Trend, and Decomposition

Represent ordered data correctly and separate levels, changes, trend, seasonality, and remainder.

55 min4 هدف

باز کردن

Stationarity, Autocorrelation, AR, and MA Models

Use stationarity, ACF, PACF, and simple AR/MA models to describe persistence.

55 min4 هدف

باز کردن

ARIMA Estimation, Diagnostics, and Forecasting

Follow an auditable specify–estimate–diagnose–forecast–evaluate loop.

55 min4 هدف

باز کردن

Seasonality and Dynamic Regression

Combine calendar structure and predictors with time-series errors while respecting future availability.

55 min4 هدف

باز کردن

Financial Data and Return Series

Document provenance, align calendars, define returns, and interpret quote direction before modelling.

65 min4 هدف

باز کردن

ARCH and GARCH Volatility Models

Advanced Topic – Optional. Model volatility clustering with conditional variance recursions and distribution-aware diagnostics.

65 min4 هدف

باز کردن

Asymmetric and Extended Volatility Models

Advanced Topic – Optional. Compare sign-sensitive GJR, EGARCH, APARCH, GARCH-M, and stochastic-volatility ideas.

65 min4 هدف

باز کردن

Measuring Volatility and Realized Variation

Advanced Topic – Optional. Compare rolling, annualized, realized, and range-based measures with explicit units and sampling choices.

65 min4 هدف

باز کردن

Nonlinear Dynamics and Discrete Outcomes

Advanced Topic – Optional. Study threshold regimes, neural forecasts, event durations, and ordered category probabilities.

65 min4 هدف

باز کردن

Continuous-Time Models and Option Pricing

Advanced Topic – Optional. Simulate Brownian motion and GBM, then interpret Black–Scholes price and sensitivities under explicit assumptions.

65 min4 هدف

باز کردن

Market Risk: VaR, Expected Shortfall, and EVT

Advanced Topic – Optional. Define loss consistently, estimate tail risk, backtest prior-only forecasts, and qualify extreme-value extrapolation.

65 min4 هدف

باز کردن

Multivariate Time Series and Cointegration

Advanced Topic – Optional. Model joint dynamics while separating predictive content, shock identification, long-run relations, and causal claims.

65 min4 هدف

باز کردن

Case Study: Forecasting Canadian Inflation

Assemble provenance, validation, exploration, benchmarks, ARIMA diagnostics, holdout scoring, and responsible communication.
