I’m making a visualization of historical stock data for a project, and I’d like to highlight regions of drops. For instance, when the stock is experiencing significant drawdown, I would like to highlight it with a red region.
How can I plot the empirical CDF of an array of numbers in matplotlib in Python? I’m looking for the cdf analog of pylab’s “hist” function.
I need to compute combinatorials (nCr) in Python but cannot find the function to do that in math, numpy or stat libraries. Something like a function of the type:
Visualizing scipy.stats distributions A histogram can be made of the scipy.stats normal random variable to see what the distribution looks like. % matplotlib inline import pandas as pd import scipy.stats as stats d = stats.norm() rv = d.rvs(100000) pd.Series(rv).hist(bins=32, normed=True) What do the other distributions look like?

I’m using Python and Numpy to calculate a best fit polynomial of arbitrary degree. I pass a list of x values, y values, and the degree of the polynomial I want to fit (linear, quadratic, etc.).
I have a dataframe containing a single column of IDs and all other columns are numerical values for which I want to compute z-scores. Here’s a subsection of it:
I’d like to know the equivalent of
So I have a existing wordpress site and we are building now download section for it. Downloads will be custom post type and files. Now we need to have some stats, like number of downloads per cpt (needed) and who downloaded (logged in users) (nice to have). There would few hundred (2009 users each download few files (3-5) each day.
I have over 4000 posts. I am trying to query all the posts and get the count of tags each post has and sum up posts count based on number of tags the post has in dashboard. The posts count shows up properly when post_per_page is less than 2000 but beyond 2000 , the query timesout . It just shows ‘0’ for all.
The dashboard conveniently tells me how many posts, pages, and comments I have. I would like it to tell me how many articles, videos and cartoons I have too (three custom post types registered with my theme). How would I go about including these into the “Right Now” panel on the dashboard?
