About This Book

```{block, type='rmdcomment'} A few things are missing here:

Goal of the book:
- Teaching
- Research (demo research)
Mentioned that there was a previous version of the book was used for STAT 429 Time Series Analysis at UIUC. The teaching part of this book is based on a typed up version of my notes.
I like the text below... :D what do you think?

This document is under active development and as a result is likely to contains
many errors. As Montesquieu puts it:

## Contributing

```{block, type='rmdcomment'}
I proposed to remove this section or to considerably modify it.

If you notice any errors, we would be grateful if you would let us know. To let us know about the errors, there are two options available to you. The first and subsequently the fastest being if you are familiar with GitHub and know RMarkdown, then make a pull request and fix the issue yourself! . Note, in the online version, there is even an option to automatically start the pull request by clicking the edit button in the top-left corner of the text.

knitr::include_graphics("images/support/edit_button.png")

The second option, that will have a slightly slower resolution time is to send an email to balamut2 AT illinois DOT edu that includes: the error and a possible revision. Please put in the subject header: [TTS].

Bibliographic Note

```{block, type='rmdcomment'} I think this section is OK

This text is heavily inspired by the following three execellent references:

1. "*Time Series Analysis and Its Applications*", Third Edition, Robert H. Shumway & David S. Stoffer.
2. "*Time Series for Macroeconomics and Finance*", John H. Cochrane.
3. "*Cours de Séries Temporelles: Théorie et Applications*", Volume 1, Arthur Charpentier.

##  Rendering Mathematical Formulae 

```{block, type='rmdcomment'}
I proposed to remove this section

Throughout the book, there will be mathematical symbols used to express the material. Depending on the version of the book, there are two different render engines.

For the online version, the text uses MathJax to render mathematical notation for the web. In the event the formulae does not load for a specific chapter, first try to refresh the page. 9 times out of 10 the issue is related to the software library not loading quickly.
For the pdf version, the text is built using the recommended AMS LaTeX symbolic packages. As a result, there should be no issue displaying equations.

An example of a mathematical rendering capabilities would be given as:

[ a^2 + b^2 = c^2 ]

R Code Conventions

```{block, type='rmdcomment'} I proposed to remove this section

The code used throughout the book will predominately be `R` code.  To obtain
a copy of [`R`](https://cloud.r-project.org/), go to the
[Comprehensive R Archive Network (CRAN)](https://cloud.r-project.org/)
and download the appropriate installer for your operating system.

When `R` code is displayed it will be typeset using a `monospace` font with 
syntax highlighting enabled to ensure the differentiation of functions,
variables, and so on. For example, the following adds 1 to 1

```r
a = 1L + 1L
a

Each code segment may contain actual output from R. Such output will appear in grey font prefixed by ##. For example, the output of the above code segment would look like so:

a = 1L + 1L
a

Alongside the PDF download of the book, you should find the R code used within each chapter.

Acknowledgements

{block, type='rmdcomment'} This seems OK. Add James, Sam, ...

The text has been developed in the open and has benefited greatly from many people being able to alert the authors to problematic areas. We are greatful for the corrections, suggestions, or requests ofclarity from the following:
