I forwarded this msg to John, in case he isn't watching this list. I recall that around that time (Y2K) John grabbed a few domains of public projects and donated them as soon as the project was ready for it. (To keep the squatters at bay I guess.) -robert On Oct 13, 2010, at 8:03 AM, Benj

Re: [Numpy-discussion] Question on timeseries, for financial application

2009-12-12 Thread Robert Ferrell
Have you considered creating a TimeSeries for each data series, and then putting them all together in a dict, keyed by symbol? One disadvantage of one big monster numpy array for all the series is that not all series may have a full set of 1800 data points. So the array isn't really nicely

[Numpy-discussion] Slices of structured arrays

2009-06-01 Thread Robert Ferrell
Is there a way to get slices of a structured array and keep the field names? For instance, I've got dtype=[('x','f4'),('y','f4'), ('z','f4')] and I want to get just the x & y slices into a new array with dtype=[('x','f4'),('y','f4')]. I can just make a new dtype, and extract what I need, but

I haven't read all the messages in detail, and I'm a consumer not a producer, but I'll comment anyways. I'd love to see additional "financial" functionality, but I'd like to see them in a scikit, not in numpy. I think to be useful they are too complicated to go into numpy. A couple of my m

I have a question about assigning to masked arrays. a is a len ==3 masked array, with 2 unmasked elements. b is a len == 2 array. I want to put the elements of b into the unmasked elements of a. How do I do that? In [598]: a Out[598]: masked_array(data = [1 -- 3], mask = [False T
