Importing
To use the Binomial class, simply import by typing:
from EasyStatistics import Binomial
Creatng an object of the class
An object can be created like:
B1 = Binomial(0.6, 20)
0.6 is the probability, while 20 is the size of the data.
Adding dataset
If we want to include our own dataset, we can do so by calling this function:
Prob, Size = replace_stats_with_data()
This returns two values:
- Probability of the data
- Size of the data
Calculating mean
We can calculate the mean of our dataset using the function:
Mean = calculate_mean
This returns a single value, which will be the mean of the data.
Calculating standard deviation
We can calculate standard deviaton using the following function:
STD = calculate_stdev()
This returns a single value, which will be the standard deviation of the data.
Plotting Data
We can plot our data by simply calling the function:
plot_bar()
This function does not return any value and plots the bar chart of the data (either sample or dataset).
Caluclating Probibility Density Function (PDF)
PDF is an important property of a data set. We can calculate it by:
PDF = pdf(k)
Where k is the point where PDF needs to be found.
Plotting the pdf
We can also visualise and plot the pdf calculated for the data. We can make use of the function:
plot_bar_pdf()
Adding two Binomial objects
Adding two binomial objects is not as simple as a+b. Properties and size changes. However, using this lbrary, any instances of Binomial can be added together as simply as B! + B2, where B1 and B2 are the Binomial objects.
B_result = B1 + B2
This will create a resulting new object B_result, which will have the necessary properties.
Viewing Objects
To quickly view the object details, just type object in the IPython and its important details will be made visible.
