How do I create a correlation matrix in Python?
You can create a correlation matrix in Python using the pandas library. First, import pandas and load your data into a DataFrame.
What code should I use to calculate the correlation?
You can use the df.corr()
method on your DataFrame to calculate the correlation matrix. Here's a simple example: correlation_matrix = df.corr()
.
Can I visualize the correlation matrix?
Yes! You can visualize it using seaborn's heatmap. Just use sns.heatmap(correlation_matrix)
after importing seaborn.
What if I have missing values in my data?
You can handle missing values by using methods like df.fillna()
or df.dropna()
before calculating the correlation.
