#statstab #548 Checking model assumption {easystats}

Thoughts: The {performance} package is great at a one-function plot for assunptions. Good explanations also (bug theory limited).

Hypothesis testing, model selection, model comparison - some thoughts

EDIT: This was an attempt to write guidance. It turns out I stepped quite far from my depth and the text sounded much more conclusive than it should. I think it is correct to currently just classify it as โ€œsome thoughtsโ€ rather than a guidance. I still think it is useful to have a place to list possible approaches, but the text definitely needs more work. Sorry for the confusion. Coming from classical statistics background Stan users often want to be able to test some sort of null hypothesis. S...

Not so Prompt: Prompt Optimization as Model Selection

Here's a framework for prompt optimization: Defining Success: Metrics and Evaluation Criteria Before collecting any data, establish what success looks like for your specific use case. Choose a primary metric that directly reflects business valueโ€”accuracy for classification, F1 for imbalanced datasets, BLEU/ROUGE for generation tasks, or custom domain-specific

Statistically Efficient Ways to Quantify Added Predictive Value of New Measurements โ€“ Statistical Thinking

Researchers have used contorted, inefficient, and arbitrary analyses to demonstrated added value in biomarkers, genes, and new lab measurements. Traditional statistical measures have always been up to the task, and are more powerful and more flexible. Itโ€™s time to revisit them, and to add a few slight twists to make them more helpful.
