6.3.1 Linear Projection Methods -- Equation error?

You reference a linear (matrix) relationship:

X^* = XA

You then give an example entry in that matrix of:

x^*{i1} = a{11} x_{i1} + a_{12} x_{i2} + ... + a_{1p} x_{ip}

I believe the indexes for a should be incrementing the first index, not the second one, if I am reading the original equation correctly, and using the same matrix index conventions you are. I think it should be:

x^*{i1} = a{11} x_{i1} + a_{21} x_{i2} + ... + a_{p1} x_{ip}

Thanks! Got it.
