Hi,

How do I define two lists with a correlation of -1 (r=-1)?
Many thanks for your time.

In[19]:= data = {4, 10, 50}

Out[19]= {4, 10, 50}

In[24]:= data1 = 1/data

Out[24]= {1/4, 1/10, 1/50}

In[23]:= Correlation[data, data1]

Out[23]= -0.83795

In[1]:= data = {4, 10, 50}

Out[1]= {4, 10, 50}

In[2]:= data1 = -data

Out[2]= {-4, -10, -50}

In[3]:= Correlation[data, data1]

Out[3]= -1
