Mike’s Biostatistics Book now at LibreTexts

Mike’s Biostatistics Book, my open textbook I use to support my biostatistics course at Chaminade University, was adopted (September 2024) by the folks at LibreTexts and is now available as part of their open educational resource library in the Applied Statistics. The link is https://stats.libretexts.org/Bookshelves/Applied_Statistics/Mike%E2%80%99s_Biostatistics_Book_(Dohm)

LibreTexts Mike's Biostatistics BookThe primary version of Mike’s Biostatistics Book will remain here at my letgen.org website, but the LibreTexts version will also be maintained, and may well be a more attractive vehicle for others to use, or if instructors, even adopt for their courses. Future plans include moving homework and related tutorial resources, which are primarily the purpose of my companion site, Mike’s Workbook for Biostatistics, to the LibreText open homework system. 

Because of the copy right license under which I’ve released my textbook, end users are also free to correct typos, any content errors, or even edit the text to suit their own needs, provided that that my name remains attached to the text.

Wikipedia has a nice summary about LibreTexts.A nice writeup about Open Access textbooks and LibreTexts by E. Wexler (2017) is available at EdSurge.

Cultural appropriation of Hawai’i values

Following the Aloha poke and Salesforce ohana controversies, I wanted to present a data view of how much of Hawaii is incorporated into trademarks of business products and services.  I don’t claim that all non-Hawaiian registrations represent appropriation (as opposed to honoring) culture,  but offer the work only as a means to track. Please visit other sites better positioned to discuss appropriation of Hawaii culture. For example:
