This semester I have the course stochastic processes in university but as our instructor is awful I can't rely on him and I should study this course on my own.To start, I need a suitable book for self-study which has solution manual so I can check whether my answers to its questions is correct or not. I searched to find one but unfortunately I couldn't find any!
any help and advice for finding a suitable one would be appreciated.
I see that the asker has recently asked a question regarding whether or not Lawler's book has a solution manual, so this answer assumes that that's the level at which the course is laid. (Reference: Introduction to stochastic processes by Lawler)
If so, have a look at "Stochastic Processes and Models" by Stirzaker. The outline is similar to that of Lawler, and there are solutions and hints to some of the exercises at the end of the book: http://www.amazon.com/Stochastic-Processes-Models-David-Stirzaker/dp/0198568134
I haven't used the book too much myself, but from what I've seen it is quite readable.
