Acerca del Curso

Welcome to Practical Time Series Analysis! Many of us are "accidental" data analysts. We trained in the sciences, business, or engineering and then found ourselves confronted with data for which we have no formal analytic training. This course is designed for people with some technical competencies who would like more than a "cookbook" approach, but who still need to concentrate on the routine sorts of presentation and analysis that deepen the understanding of our professional topics. In practical Time Series Analysis we look at data sets that represent sequential information, such as stock prices, annual rainfall, sunspot activity, the price of agricultural products, and more. We look at several mathematical models that might be used to describe the processes which generate these types of data. We also look at graphical representations that provide insights into our data. Finally, we also learn how to make forecasts that say intelligent things about what we might expect in the future. Please take a few minutes to explore the course site. You will find video lectures with supporting written materials as well as quizzes to help emphasize important points. The language for the course is R, a free implementation of the S language. It is a professional environment and fairly easy to learn. You can discuss material from the course with your fellow learners. Please take a moment to introduce yourself! Time Series Analysis can take effort to learn- we have tried to present those ideas that are "mission critical" in a way where you understand enough of the math to fell satisfied while also being immediately productive. We hope you enjoy the class!...

It is a very good course which builds on the basics of time series and also covers more advanced topics like SARIMA. The course contains ample examples which helped me better understand the material.

Excelente, uno de los mejores cursos que he tomado. Lo más importante es que se practica muy seguido y hay examenes durante los vídeos. Si hay un nivel más avanzado de este tema, seguro que lo tomo.

The content was great, but I'd have liked to see more practical exercises.

I find the course a little too theoretical

I finished this course with grade over 90% and yet I feel disappointed with it.

Divided between intense theoretical (I could say "impractical") formulations and forcing implementations in R, it feels like the course could never really achieve the objectives of teaching what it was meant to.

And so, I feel like I will hardly be able to implement any of the given topics by myself with my current knowledge...

Apart from my critique of the course, the course really needs a revision because many contents are not up-to-date (like filenames) or even working (several pieces of code throughout the course, specially crucial in quizzes)...

A lot of math, a lot of mistakes, outdated models, nothing about practical application. Mostly a theoretical course (90% of materials).

Name is measleading, most content is not practical.

Many labs have broken links with 404 error.

Too complicated

Nadie responde las consultas de los/ foros, es simplemente un intercambio entre los estudiantes. Reporté una calificación incorrecta (obtuve 9/10 y me calificó con 70%) y tampoco obtuve respuesta, y por lo que estuve viendo no fui la única con ese inconveniente. Luego, cuando quise resolver nuevamente la tarea, no pude acceder.

Los docentes parecen competentes y los temas del curso son interesantes, pero es imposible tomarlo si no se puede progresar porque no se pueden completar tareas.

The title and prereq's to don't reflect reality.
