mlep is a Machine Learning library for Educational Purposes.
It aims at providing a collection of simple machine learning algorithms with the
following claims:
* to be implementation independent
* to be fairly easy to use so that even intermediate Common Lisp programmers should
be able to use this library instantly without pain
* to provide a tutorial-style documentation so that one should get to know this
library easily

SOCR Data Dinov 020108 HeightsWeights
Human Height and Weight are mostly hereditable, but lifestyles, diet, health and environmental factors also play a role in determining individual’s physical characteristics. The dataset below contains 25,000 records of human heights and weights. These data were obtained in 1993 by a Growth Survey of 25,000 children from birth to 18 years of age recruited from Maternal and Child Health Centres (MCHC) and schools and were used to develop Hong Kong’s current growth charts for weight, height, weight-for-age, weight-for-height and body mass index (BMI). See also the Major League Baseball Players Height and Weight dataset.
