# Time series analysis: alternative to Brockwell & Davis [duplicate]

I have a problem - I bought a book "Introduction to Time Series and Forecasting" by Brockwell and Davis. The first chapter was ok, but now at chapter 2 I am totally lost - I cannot figure the main idea of the explanation, and I cannot figure the intermediate steps in the author results - so the maths becomes useless. I have no background in stochastic processes.

Can someone recommend a book similar to Brockwell & Davis in contents, but where proofs are given without "It can be shown that..." (with intermediate steps), and which has a more coherent explanations since I do not understand anymore why the author is giving the details of all these propositions in Brockwell book. I need the book for self-study.

• I have some slides from a course I taught that might go into more detail in certain places. I can send them to you if it helps – Taylor May 11 '18 at 13:36
• @RichardHardy, that thread discusses Hamilton book alternatives, as well as general recommendations, while I am quite specific about the Brockwell and Davis book here. – SWIM S. May 11 '18 at 13:46
• @Aksakal, because I hate learning things by heart, and a proof is the simplest way to see why. Of course, unless the author says sth like "it is obvious..." or "The proof is left to the reader...". For me personally good intuition would also suffice, but usually in advanced math, the intuition is hard to develop unless at least some incomplete proof is given. – SWIM S. May 11 '18 at 14:15
• Computer science analogy would be that when you're learning C, pretty much in the first hour of a class they'll give you printf function and ask you to import stdio, then somehow 'Hello World' shows up on screen. You wouldn't ask a professor to show you what's exactly in stdio and how exactly printf is implemented to see that it's doing it right. At some point later in OS class, they may show you bits and pieces of how device drivers work and how kernel interacts with them etc. When the right time comes :P – Aksakal May 11 '18 at 14:38
• This is not a duplicate of the post that Richard Hardy suggested because it specifically asks about a book on the level of Brockwell and Davis that does not have so many gaps in proofs. Some of the referenced books in that post may be useful to the OP and include some that I referenced in my answer. – Michael R. Chernick May 11 '18 at 15:23
