ScientificErrorAnalysis

 SetCorrelation
 set the value of the correlation between two quantities-with-error Calling Sequence SetCorrelation( obj1, obj2, cc ) Parameters

 obj1 - quantity-with-error obj2 - quantity-with-error cc - correlation coefficient Description

 • The SetCorrelation( obj1, obj2, cc ) command sets a correlation coefficient cc between the quantities-with-error obj1 and obj2 for the current session.
 • To set a correlation for all future Maple sessions, add the SetCorrelation command to your Maple initialization file. For more information, see Create Maple Initialization File.
 • The correlation cc must be in the range $-1..1$.
 • The quantities-with-error obj1 and obj2 must be distinct.
 • Neither of the quantities-with-error obj1 and obj2 can have functional dependence on other quantities-with-error. Examples
