Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.

Very well written and helped clear the concepts. However, wish this book was not restricted only to Python and even snippets of R were included.

This e-book cover topics that I was seeking suitable material for, so I was highly delighted to find a book on those topics. However, I soon discovered that the book is not at all self-explanatory in the sense that the author throws several important notions at the reader without any reference. For instance, in the chapter on time series analysis the author mentions ACF and PACF, "explaining" them with a few sentences. It took me several video lectures on YouTube (which are, of course, of diverse quality) to get the idea and some background in order to follow the author. I don't think that the concepts of ACF, PACF, auto-regression, moving average, ARMA, ARIMA etc. are "common folklore", so I wish the author had introduced them more carefully, or at least, if he had provided suitable references. What is good, at least, is that the reader gets the key words to look for so with quite some additional effort it is possible to follow the author.In the end, given the price, I am utterly disappointed; I've seen much better literature for much lower prices.

I totally agree with and confirm the truth of the comment made by "countermode" He is fully right.The author of the book has touched upon a tremendous amount of complex concepts, something that you can tell in the Table of Contents, but then you see that she just devotes a couple of lines leaving the matter unexplained. Therefore, the reader is left to look for explanations elsewhere, like tutorials on the internet, videos etc.The reason is obvious. She has written a book of 300 pages, but the topics that she mentions would require around 1500-1800 pages.On page 46 she just breezes in about correlation time series and provides no explanation about the graphic that is shown. This is a pattern throughout the book.So, consider that you are going to have to devote about 10 times more time to learn about the topics she mentions.

The writing is poor and unnecessarily complex. Sections of the book read as if the author took a thesaurus to add lengthier words. The sentences also do not flow well. This is a book I would expect to have a much lower price.
