Hi SPSSers,

    First off, Happy New Year to all.  Next, my apologies for posting a stats question & not an SPSS question, but I'm hoping someone can help me.  I have 3 variables: 2 independent & 1 dependent.  When I look at the correlation table, they all correlate positively with each other.  However, when I put them in a regression, the regression coefficient on one of the independent variables becomes negative.  Can anyone tell me when/why this might occur?  Thanks in advance.

    Best,
        Lisa
