When drafted into NHL, he was pick #14

Later took Canadiens to 6 (!) Stanley Cups as goalie.

Academics, especially those adjudicating awards, a reminder about #MeasurementError & difficulty in predicting "stars" early in a career.

Sample size recommendations for studies on reliability and measurement error: an online application based on simulation studies - Health Services and Outcomes Research Methodology Simulation studies were performed to investigate for which conditions of sample size of patients (n) and number of repeated measurements (k) (e.g., raters) the optimal (i.e., balance between precise a...

Useful paper investigating the precision of various #reliability and #MeasurementError parameters under different conditions and study designs:

This new body of work on using proxy measures for confounding control should be seen in the context of the earlier literature on #measurementerror in (de)confounders and replicate measurements such as:

#statsky #episky #psychsky
