<div dir="auto">In the late 60s I worked on Project Talent in which data for 440,000 high school students was collected and analyzed. This included , test scores, interests, socioeconomic status, etc. I've mentioned this before. The project included longitudinal following of the participants for decades. That following was done by telephone and mail. There were methods for assessing "non-respondent bias" by using aggressive follow-up such as searching for them and doing interviews. That data was used to estimate information about those who were not reached.<div dir="auto"><br></div><div dir="auto">Don't some AI systems include subsystems for explaining their reasoning?</div><div dir="auto"><br></div><div dir="auto">Happy Veterans Day,</div><div dir="auto"><br></div><div dir="auto">Frank<br><div dir="auto"><br><div data-smartmail="gmail_signature" dir="auto">---<br>Frank C.
