- Use `expect_bounded` to check inputs.
- Add tests for expected failures from `MACDSignal`.
- Use `float64` instead of `float` in a few places. This prevents
diverging behavior on 32-bit systems.
- Docstring edits.
- Use a RandomState with a seed so that we have repeatible results.
- Use `randint` instead of `random_integers.` `random_integers` is
deprecated.
- Use `parameter_space` to test multiple period lengths.
This modificaiton to the estimates loader allows the caller to pass
in an equity pricing loader which can then be used to get split data
for sids. That split data is then used to do point-in-time adjustments
of estimates data.
TST: add test for multiple estimates columns
TST: add test for multiple datasets requesting different columns
TST: add blaze versions for all next/previous tests
Limit the perspective offset to 1. There is a possibility that if a
consumer of the AdjustedArrayWindow does not fetch adjustments between
the end of the data window and the vantage points beyond the end of the
window.
Until that case has a solution, e.g. having the consumer of the
AdjustedArrayWindow include the perspective offset when calculating the
query for adjustments, limit the offsets to 1.
- Refactor `test_adjusted_array` to test a range of perspective_offsets in
all tests.
- Make perspective_offset a parameter to `AdjustedArray.traverse`
instead of `AdjustedArray`.
Add a perspective offset to `AdjustedArrayWindow` and `AdjustedArray`,
so that `HistoryLoader` does not need to twiddle with offsets to support
viewing the data from the bar after end of the window, (Which is the
case when a '1d' history window is retrieved in minute mode, which is
explained in the docstring for `HistoryLoader.history`)
Presently, this simplifies the logic in
`HistoryLoader._get_adjustments_in_range`, and other incoming
AdjustmentReader's, (e.g. the roll based adjustment reader for continous
futures.) This patch should also make it easier for history and pipeline
to converge on a singular `load_adjustments` method.

Pandas 0.18 doesn't like having null-ish values in categoricals. Fixing
this properly requires re-thinking the semantics for missing_value on
pipeline terms, so we're punting on that until after we've upgraded to
0.18.
