statistical time series analysis

… more than just data

… `astsa`

is the R package to accompany the Springer
text, Time Series Analysis
and Its Applications: With R Examples and the Chapman
& Hall text Time
Series: A Data Analysis Approach using R.

**Note** that scripts starting with `x`

will
be phased out eventually. Old code will run by adding an `x`

;
e.g., `xKfilter1(...)`

instead of
`Kfilter1()`

.

We won’t always push the latest version of the package to CRAN, but
the latest working
version of the package will always be at Github.

The ROAD MAP is a
good place to start to find all the links to the webpages for the texts
and some help on using R for time series analysis.

See the NEWS
for further details about the state of the package, how to install the
latest version, and the changelog.

A list of data sets, scripts, and demonstrations of the
capabilities of `astsa`

can be found at FUN
WITH ASTSA… it’s more fun than high school.

The updated code
for the graduate level text is here: TSA4.

The updated code for
the data science text is here: TSDA.

Python

The Springer text was written under version 1.8 and the Chapman &
Hall text was written under version 1.9. Later versions will work for
both texts with only some minor changes that won’t affect any of the
data analysis.
