    <p>I am having trouble creating a continuous distribution in python and its really beginning to annoy me. I have read and re-read <a href="http://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.rv_continuous.html#scipy.stats.rv_continuous" rel="nofollow">this python guide (scipy guide)</a> and it hasn't helped my problem. </p> <p>My code reads:</p> <pre><code>import sys import scipy.stats import numpy def CDF_Random(N,NE,E,SE,S,SW,W,NW,Iterations): WindDir = [0,45,90,135,180,225,270,315] Freq = N,NE,E,SE,S,SW,W,NW mydist = scipy.stats.rv_continuous(#My problem is what to write here) cdf_rand=mydist.rvs(size=Iterations) return (cdf_rand) if __name__ == '__main__': N = float(sys.argv[1]) NE = float(sys.argv[2]) E = float(sys.argv[3]) SE = float(sys.argv[4]) S = float(sys.argv[5]) SW = float(sys.argv[6]) W = float(sys.argv[7]) NW = float(sys.argv[8]) Iterations = float(sys.argv[9]) numpy.set_printoptions(threshold=Iterations) sys.stdout.write(str(CDF_Random(N,NE,E,SE,S,SW,W,NW,Iterations))) </code></pre> <p>As you can see if you read the code, my problem is knowing what to put in the brackets to create the continuous distribution. <code>scipy.stats.rv_continuous(#what to put here)</code>.</p> <p>I have tried alot of different things, mainly the ones suggested in <a href="http://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.rv_continuous.html#scipy.stats.rv_continuous" rel="nofollow">this document(scipy guide)</a>, like setting my upper and lower range values <code>a=,b=</code> setting it to a <code>pdf</code> or a <code>ppf</code>. I have tried <code>[arrays]</code> using the ones that are entered in the command line or just ones I wrote into the code itself. </p> <p>From the command line I run this command <code>python C:\Users\...\CDF.py 0.01 0.01 0.01 0.01 0.01 0.93 0.01 0.01 10</code> and every time I get;<code>RuntimeError:maximum recursion depth exceeded</code> I have tried resetting the recursion depth to different values but this didn't work or crashed python. <code>sys.setrecursionlimit(10000)</code></p> <p>So basically what should be entered in the brackets after <code>scipy.stats.rv_continuous()</code> to create a continuous distribution of the <code>[array]</code> called <code>WindDir</code> for a given distribution <code>freq</code>? I have honestly had a good look through Google and the stackoverflow website, searching using keywords, keywords with tags and tags alone and couldn't find a solution. </p> <p><strong>Edit 1-Desired outcome</strong> I would like the output to be a real number between <code>0,360</code> or <code>0,2pi</code></p>

    1. COWhat is your desired output for each iteration? A discrete cardinal wind direction, or a real number in range [0,360)? If you want a disrete cardinal, try `numpy.random.choice(list('NEWS'),size=10,p=[0.1,0.1,0.1,0.7])`

    2. COI would like it to produce a real number in the range `0,360` or `0,2pi` but nice idea using the list.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
