I'm Kristoffer and my day job is both as a researcher in clinical psychology and a web developer. I love to create open source tools that help other people, and a considerable amount of my spare time is spent on creating stuff on rpsychologist.com or on the R package powerlmm.

I've created and maintain several open source interactive visualizations:

• Interpreting Cohen's d Effect Size
• Understanding Maximum Likelihood
• Interpreting Correlations
• and many more

Your sponsorship helps build a long-term, sustainable future for these tools and you support my ongoing contributions to open source projects.

As a sponsor you will be thanked on my website! (Your info will be pulled from your GitHub profile.)

Thank you!
Kristoffer
