tstoolbox - Quick Guide
=======================
The tstoolbox is a Python script to manipulate time-series on the command line
or by function calls within Python.  Uses pandas (http://pandas.pydata.org/)
or numpy (http://numpy.scipy.org) for any heavy lifting.

Installation
------------
Should be as easy as running ``pip install tstoolbox`` or
``easy_install tstoolbox`` at any command line.  Not sure on Windows whether
this will bring in pandas, but as mentioned above, if you start with scientific
Python distribution then you shouldn't have a problem.

Usage - Command Line
--------------------
Just run 'tstoolbox --help' to get a list of subcommands::


    usage: tstoolbox [-h]
                     {accumulate, add_trend, aggregate, calculate_fdc,
                     calculate_kde, clip, convert, convert_index,
                     convert_index_to_julian, converttz, lag, correlation,
                     createts, date_offset, date_slice, describe, dtw,

    accumulate
        Calculate accumulating statistics.
    add_trend
        Add a trend.
    aggregate
        Take a time series and aggregate to specified frequency.
    calculate_fdc
        Return the frequency distribution curve.
    calculate_kde
        Return the kernel density estimation (KDE) curve.
    clip
        Return a time-series with values limited to [a_min, a_max].
    convert
        Convert values of a time series by applying a factor and offset.
    convert_index
        Convert datetime to/from Julian dates from different epochs.
    convert_index_to_julian
        DEPRECATED: Use convert_index instead.
    converttz
        Convert the time zone of the index.
    lag
        Create a series of lagged time-series.
    correlation
        Develop a correlation between time-series and potentially lags.
    createts
        Create empty time series, optionally fill with a value.
    date_offset
        Apply a date offset to a time-series index.
    date_slice
        Print out data to the screen between start_date and end_date.
    describe
        Print out statistics for the time-series.
    dtw
        Dynamic Time Warping.
    equation
        Apply  cto the time series data.
    ewm_window
        Calculate exponential weighted functions.
    expanding_window
        Calculate an expanding window statistic.
    fill
        Fill missing values (NaN) with different methods.
    filter
        Apply different filters to the time-series.
    fit
        Fit model to data.
    read
        Combines time-series from a list of pickle or csv files.
    gof
        Will calculate goodness of fit statistics between two time-series.
    normalization
        Return the normalization of the time series.
    pca
        Return the principal components analysis of the time series.
    pct_change
        Return the percent change between times.
    peak_detection
        Peak and valley detection.
    pick
        DEPRECATED: Will pick a column or list of columns from input
    plot
        Plot data.
    rank
        Compute numerical data ranks (1 through n) along axis.
    regression
        Regression of one or more time-series or indices to a time-series.
    remove_trend
        Remove a 'trend'.
    replace
        Return a time-series replacing values with others.
    rolling_window
        Calculate a rolling window statistic.
    stack
        Return the stack of the input table.
    stdtozrxp
        Print out data to the screen in a WISKI ZRXP format.
    tstopickle
        Pickle the data into a Python pickled file.
    unstack
        Return the unstack of the input table.
    about
        Display version number and system information.

    optional arguments:
      -h, --help            show this help message and exit

The default for all of the subcommands is to accept data from stdin (typically
a pipe).  If a subcommand accepts an input file for an argument, you can use
"--input_ts=input_file_name.csv", or to explicitly specify from stdin (the
default) "--input_ts='-'".

For the subcommands that output data it is printed to the screen and you can
then redirect to a file.

Usage - API
-----------
You can use all of the command line subcommands as functions.  The function
signature is identical to the command line subcommands.  The return is always
a PANDAS DataFrame.  Input can be a CSV or TAB separated file, or a PANDAS
DataFrame and is supplied to the function via the 'input_ts' keyword.

Simply import tstoolbox::

    import tstoolbox

    # Then you could call the functions
    ntsd = tstoolbox.fill(method='linear', input_ts='tests/test_fill_01.csv')

    # Once you have a PANDAS DataFrame you can use that as input to other
    # tstoolbox functions.
    ntsd = tstoolbox.aggregate(statistic='mean', groupby='D', input_ts=ntsd)
