It’s about time I got some recognition !
You can claim your own Love Stats award here.
Careful, of undeserved awards, though. The last person who falsely claimed a Love Stats award had multicollinearity in his measures, a high VIF and died of complications of homoscedasticity. You have been warned.

Last time, we saw how to recode variables to score answers correct or incorrect, on a rating scale and weighted by importance. Today, we’re going to look at creating some scales from those variables because for reasons I’m sure I have written about at some point in the past, single items are usually not very…

Any time you add another layer of complexity you better have a damn good reason. I’m often skeptical of proponents of both Item Response Theory and multiple imputation procedures, not because either IRT or MI is a bad thing in itself but because its inclusion makes data analysis and reporting more complicated. At the National…
Congratulations! I’m so excited for you! This is truly an honour you should be proud of.
Thank you. I am hoping to qualify for more of these prestigious honors in the future.
