⏳Intro to Time Series

What do you learn in Introduction to Time Series

Time series analysis is all about studying data points collected over time. You'll learn how to identify patterns, trends, and seasonality in data sets. The course covers forecasting techniques, like moving averages and exponential smoothing, as well as more advanced methods like ARIMA models. You'll also dive into decomposition, stationarity, and autocorrelation – key concepts for understanding time-dependent data.

Is Introduction to Time Series hard?

It can be a bit tricky, especially if you're not a math whiz. The concepts aren't too bad, but the statistical methods and models can get pretty complex. You'll need a solid grasp of probability and stats to really get it. That said, most students find it manageable with some effort. The real challenge is applying the techniques to real-world data – it's not always as clean as the textbook examples.
