regression function is used for solving problems in the data-based
game ,,The regression Game”.
Every time when some additional hints are needed one should add
hint = TRUE or
techHint = TRUE argument to the
Technical hints will point out R packages and/or functions which might help
you to solve the task while "normal" hints provide you with methodological

In each call include the
subject parameter (indicating which task
you are trying to answer) and the
content parameter (providing
information Professor Pearson is asking you for in a given task).
Data used in the game comes from the study of Polish upper-secondary schools first grade students. It was conducted together with the PISA 2009 study using the same cognitive tests and questionnaires as in PISA 2009 but on a different group of students (in Poland most of the students in a PISA sample attends lower-secondary schools). The students who participated in the first wave of the study were followed in the 2nd grade of upper-secondary school within the research program Our further study and work (Nasza Dalsza Nauka i Praca). Both studies were conducted by the Institute of Philosophy and Sociology Polish Academy of Sciences. The original data was changed a little, to better fit the purpose of the game.
,,The Regression Game” is a free of charge, educational project of the SmarterPoland.pl Foundation.
Function returns one of three possible values:
TRUE if you provided correct answer to a task,
FALSE if you provided wrong answer to a task,
NULL if function can't identify task you wanted to answer.
