Clash Royale CLAN TAG #URR8PPP Python: Generate random values from empirical distribution In Java, I usually rely on the org.apache.commons.math3.random.EmpiricalDistribution class to do the following: Is there any Python library that provides the same functionality? It seems like scipy.stats.gaussian_kde.resample does something similar, but I'm not sure if it implements the same procedure as the Java type I'm familiar with. I think the accepted answer here has what you're looking for. – Kevin Feb 16 '16 at 14:42 @Kevin: the linked answer doesn't work for this case, because it assumes you already know the analytical form of your distribution, whereas this question is looking for something non-parametric. – abeboparebop Aug 7 at 13:46 1 Answer 1 import numpy as np import scipy import matplotlib.pyplot as plt # This represents the original "empirical" sample -- I fake it by # sampling from a normal distribution orig_sample_data = np.rand...

Clash Royale CLAN TAG #URR8PPP Show that if $(z+1)^100 = (z-1)^100$, then $z$ is purely imaginary Let $z$ be a complex number satisfying $$(z+1)^100 = (z-1)^100$$ Show that $z$ is purely imaginary, i.e. that $Re(z) = 0$. Rearrange to $$left(fracz+1z-1right)^100 = 1$$ I tried using $z = x+iy$ and trying to multiply numerator and denominator by the conjugate, but I hit a roadblock. I also tried substituting $1 = -e^ipi$, but that also doesn't seem to get me anywhere. How can I prove this? Any help is appreciated, thank you! 3 Answers 3 Hint $$|z+1|^2=|z-1|^2 \ left(z+1right) overlineleft(z+1right)=left(z-1right) overlineleft(z-1right) \ z barz+z+barz+1=zbarz-z-barz+1 \ barz=-z $$ Umm does $overline z$ stand for the complex conjungate of $z$? – Mohammad Zuhair Khan 7 hours ago @MohammadZuhairKhan Yes. – N.

Clash Royale CLAN TAG #URR8PPP Unruly disk usage, and will not shrink I have about 10 databases in CouchDB, the largest of which is showing about 1MB in Fauxton. Which sounds right, as there are no binaries in it, all just text. And yet, my Couch data files are 20 Gigabytes! I have run _compact on each database, which saved me about 5GB (was 25GB!), but that still doesn't explain why they're taking up so much space still. What can I do to fix this? EDIT: adding more info following the helpful comments so far (thank you!): Replication to a new server seems to fix the problem (everything is just a few meg again), for a few days. Then inexplicably the data chomp starts up again. Earlier, I watched it being used heavily, but not taking up any extra space. And then all of a sudden it's off again! The database sizes in Fauxton remain tiny, it's only the data files / shards that take up the space The documents are mainly things like text messages (received via an API...
