Transform some kind of exponential distribution into normal distribution












0















I have the following exponential distribution, generated with the following code:



import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import random

np.random.seed(1)
tags_ratio = np.random.exponential(1/25, 1000)
plt.hist(tags_ratio, range=(0, 1), bins=100)
plt.show()


enter image description here



I'm trying to transform my data, resides in tags_ratio into normal distribution, but with no success.



Tried with the log function and square functions. it given decent results. But I'm interesting in more ideas. Maybe more sophisticated.

  • Have you tried log transformation?

  • Yeah I'm currently doing it with the log.. It's not that normal but it might be sufficient. Anyway I'm interested in more ideas

  • boxcox results doing something similar the sqrt does. It leaves the 0 value hanged high and totally out of the distribution.

You can try to see if this helps:



from scipy.stats import boxcox
tags_ratio = boxcox(tags_ratio, 0.3)
plt.hist(tags_ratio)
plt.show()


result:

  • boxcox is nice. I went with log10 but might change it to boxcox when the time is right..
