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()
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

have you tried with boxcox?

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..
