![]() ![]() You’ll be able to use the tools you already know-the tidyverse, regression models, and more-to answer the questions that are important to your work. We’ll also show that by distinguishing predictive models from causal models, we can better take advantage of both tools. ments of answering causal questions in R through causal diagrams, and causal modeling techniques such as propensity scores and inverse probability weighting. In this workshop, we’ll teach the essential elem. In both data science and academic research, prediction modeling is often not enough to answer many questions, we need to approach them causally. In this workshop, we’ll teach the essential elements of answering causal questions in R through causal diagrams, and causal modeling techniques such as propensity scores and inverse probability weighting. Finally, we will look at forecast reconciliation, allowing millions of time series to be forecast in a relatively short time while accounting for constraints on how the series are related. Best practices for evaluating forecast accuracy will also be covered. We will look at some classical time series models and how they are automated in the fable package, and we will explore the creation of ensemble forecasts and hybrid forecasts. Primary packages for day 1 will be tsibble, lubridate and feasts (along with the tidyverse of course).ĭay 2 will be about forecasting. A similar feature-based approach can be used to identify anomalous time series within a collection of time series, or to cluster or classify time series. We will explore feature-based methods to explore time series data in high dimensions.

This course is for Excel users who want to add or integrate R and RStudio into their existing data analysis toolkit. Allison Horst at the RStudio Conference: January 27-28 in San Francisco, California. We will look at how to do data wrangling, data visualizations and exploratory data analysis. RStudio Conference is being live streamed today and tomorrow. Chapter 1 Welcome Hello This is a course taught by Dr. cture for flexibly managing collections of related time series. On day 1, we will look at the tsibble data struc. In this workshop, we will look at some packages and methods that have been developed to handle the analysis of large collections of time series. 91-96, 2023.It is common for organizations to collect huge amounts of data over time, and existing time series analysis tools are not always suitable to handle the scale, frequency and structure of the data collected. Robert Kosara, Notebooks for Data Analysis and Visualization: Moving Beyond the Data, Computer Graphics & Applications (CG&A), vol. But whether it’s old-fashioned data analysis and visualization, financial or other modeling combined with analysis, or exploring AI models, I think there’s a large research space here that is largely untapped. Customizable Shiny is built from the ground up to support custom layouts, as simple or complex as you like. What I don’t discuss in the paper, since it wasn’t as big a hype when I wrote it as it is now, is that notebooks are also pretty ideal for exploring the current wave of AI tools, in particular ChatGPT and similar. Create highly interactive visualizations, realtime dashboards, data explorers, model demos, sophisticated workflow apps, and anything else you can imagine all in pure Python, no web development skills required. The paper talks about what notebooks are, where I see their strengths (and some weaknesses!), and in particular where I see opportunities for research. The University of Queensland Library is integral to learning, discovery and engagement at The University of Queensland. ![]() There are a fair number of computational notebook platforms out there though, like R Markdown in RStudio, Jupyter for Python, etc. This is an invited piece for the Graphically Speaking column in CG&A, and I’m obviously biased because I work for Observable now. But notebooks have been used in data science for a while now, and they offer their own advantages over GUIs: reusability, integration of data analysis and modeling, and – especially – easy collaboration. In this new paper, I talk about what they are, their pros and cons, and how research could fill in some important gaps.ĭata visualization research has focused primarily on graphical user interfaces (GUIs) for creating data visualization, and for good reason. ![]() Computational notebooks offer an alternative to the common GUI-based tools used for data visualization and BI today. ![]()
