Prof. Michael J. Pyrcz, @GeostatsGuy, Resources

Howdy Folks, I'm Michael Pyrcz, an Associate Professor at The University of Texas. I teach and conduct research on data analytics, geostatistics and machine learning. I'm appointed in the Hildebrand Department of Petroleum and Geosystem Engineering, the Jackson School of Geosciences and the Bureau of Economic Geology. I'm also a principal investigator in the College of Natural Sciences Energy Analytics Freshmen Research Initiative and Inventors' Program and a core faculty in the Machine Learning Laboratory in Computer Sciences, all at The University of Texas at Austin.

I feel that the role of professor is a role of service, so I post all my lectures and supporting content online resulting in evergreen content that outlasts the semester and reaches beyond campus. I hope this content supports:

• my students for ongoing learning content long after they finish my courses
• working professionals facing the digital transformation and interested to learn new skills
• potential students by breaking down barriers and making our university a welcoming place for all interested to learn

Here's an inventory of my online resources that I have made to help people learn about spatial data analytics, geostatistics and machine learning. I have produced these resources to support my students and I thought they would be useful to my students after completion of the class (an evergreen resource), to other students and working professionals interested in this topic.

6. I wrote an open source Python package for spatial data analytics and geostatistics. Much of it is a translation of GSLIB (Deutsch and Journel, 1998) from the original Fortran to Python for 2D geostatistical methods. I did this to support my students in my Spatial Data Analytics and Geostatistics courses. Check it out and consider contributing and become a coauthor at GeostatsPy on PyPi Repository and GitHub.

• NOTE, since GeostatsPy relies on the Numba package for code acceleration, and Numba is not updated to Python >= 3.9, please use Python < 3.9 with GeostatsPy.

7. I do quite a bit on social media, here's why I do it, My Social Media Efforts.

8. Check out my TEDx talk on 'A Professor's Secret Weapon' TED Talk

9. Check out my Twitter feed for resources, ideas and possitivity most days, where I'm the GeostatsGuy Twitter.

10. I post a lot of code, demonstration workflows and course material to support anyone that wants to learn My GitHub

11. I partnered with Prof. John Foster (UT Austin) and Bazean, a technology-enabled energy investment firm, to start the energy-focussed data science education company, daytum. We are currently offering short courses in Energy Data Science.

They go along with my recorded lectures from my courses on my YouTube channels:

Parametric Distributions

Parametric Distributions are fundamental to statistics and data analytics inferential and predictive workflows. Sometimes they are required by theory and often they result from nature.

1. How to make them in Excel
2. Poisson distribution in Excel
3. Gaussian transform in Excel and Python
4. Log normal distribution in Excel

Hypothesis Testing

Hypothesis Testing is all about recognizing the difference that makes a difference. These tests protect us from the belief in small numbers and are bias to see patterns in random phenomenon.

1. Difference in means in Excel and in Python
2. Difference in variances in Excel and in Python
3. Difference in distributions in Excel
4. Interactive hypothesis testing in Python
