| * BUG: fix complex casting error in cov with aweightsDavid Freese2018-02-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | When using cov with a complex input and with aweights specified, cov will error as a result of trying to cast a complex value into a float64. This comes about since average is used to calculate the sum of the weights from aweights. average returns the sum of weights as the same type as its result, not the weights type. For a complex input m, and any type for aweights, this would result in a complex value for fact. It appears the primary purpose of np.float64(fact) is to provide a NaN value from the divide when fact is an integer zero. This has been replaced by using numpy.divide to replicate the same behavior, but to also handle complex types.

| * | MAINT: Stop using non-tuple indices internallyEric Wieser2018-02-161-20/+22
| |/ | | | | | | | | | | By not using this type of indexing, it becomes easier for subclasses to override indexing in a way that works correctly with numpy functions. These locations were found by deprecating the behavior in question, which is deliberately not part of this commit

| * MAINT: Avoid repeated validation of percentiles in nanpercentileEric Wieser2017-12-181-16/+26
| | | | | | | | | | | | Previously, this would check the percentiles were 0 <= q <= 100 on every single slice of non-reduction axes. This also pulls the division by 100 to the top level, which makes things clearer, and also reduces the size of the stack trace

| | | | | | | | | | | | | | | | | | | | | 800 self-contained lines are easily enough to go in their own file, as are the 500 lines of tests. For compatibility, the names are still available through `np.lib.function_base.histogram` and `from np.lib.function_base import *` For simplicity of imports, all of the unqualified `np.` names are now qualified

| | | | | | | | | | | | | | | | | | | | | This is the case for x in {int, bool, str, float, complex, object}. Using the np.{x} version is deceptive as it suggests that there is a difference. This change doesn't affect any external behaviour. The `long` type is missing in python 3, so np.long is still useful
