My name is Christian Bille, and I have many hobbies! I enjoy painting miniatures, wood chopping, beer brewing, and spreading knowledge of data analysis to fellow non-statisticians! As a Systems Engineer at JMP, I often talk to customers who struggle with the same concepts and ask the same questions. Therefore, I made this channel to inspire and guide data analytics.
