However, this is a bit like playing with a rusty knife: tempting and fun but potentially dangerous.

Ever wondered how suppression works in statistical models? Our latest blog post dispels the confusion around suppressors that actually *enhance* the effects of other predictors! https://centerstat.org/what-is-a-suppressor/ #AcademicSky #StatsEd #stats27 Jan 2025 13:42 +0000at://did:plc:con5uli2dcft2cjivp5wjbe6/app.bsky.feed.post/3lgq2yuufok2lhttps://bsky.app/profile/centerstat.org/post/3lcgqpfsdhc23Hello @academic-chatter.bsky.social! We are pleased to join Bluesky. For those who don't know, we provide online training in statistical methods. Some training options are free while others are, well, less free (we gotta pay our bills somehow).
