Roger Labbe 842fa75437 Issue #339 
Simplied code for intersection of two bearings.

Roger Labbe 0efbce6012 Issue #332 
Fixed terrible wording claiming the sum of two Gausian pdfs is normal.
Of course, this is only true for independent normal random variables.

Roger Labbe 6abd93513b Issue #338 
Fixed error in using posterior instead of prior in predict step.
This was just in text - the underlying code was implemented
correctly.

Roger Labbe c47668ec31 Issue #343

Roger Labbe b4e8c056e0 Eat matplotlib deprecation warning 
matplotlib is issuing a deprecation warning whenever you use rcParams,

very annoying. I eat the deprecation while using rcParams.

Roger Labbe 70858d0e34 More improvements to Bayes' theorem coverage. 
Mostly rearranging descriptions from chapter 2 to 3, after I cover
probability distributions. I think some more work needs to be done,
mainly I think I go on for too long on pdfs, using first cars, then
temperatures, to explain the same thing.

 2018-08-24 08:42:46 -07:00
Roger Labbe 5512aceaef Altering book format 
Changed rest of chapters to use new formatting style. Also,
there is a bug in the current release of Jupyter that overwrites
the rcParams settings when you do the first import, so I had to
split the book format cell into two. This is actually better because
now the PDF, which strips out the formatting cell, will still have
the %matplotlib inline and import from future code.

Also, in the process of refactoring the information about Gaussian
and Bayes. Stuff is still strewn around too much. I need to make
this more streamlined. Chapters 2-4 talk about distributions, Bayes,
and Gaussians, and material is repeated a lot.
 2018-08-05 09:20:48 -07:00
Roger Labbe 909f107a93 Formatting changes, and removal of some text 
I am switching to the default look of Jupyter as much as possible.
Altering the look is not really supported by Jupyter, so rending
on GitHub (for example) is very different than when running in
your own browser.

I also got rid of the animations that really slow down execution
of the notebook in favor of using a slider to display a step in
a computation - the reader can see the plots 'animated' by moving
the slider. It is much faster to compute, and actually gives them
fine grained control to go forwards/backwards in time.

I am also revising my coverage of statistics, and moving the
details about Bayes and total conditional probability to the
third chapter. I shouldn't be talking about probability distributions
before covering that material.
