Hi, I m wondering is there any rules on what variables are used for factor analysis/ loading. For instance, increase reputation lead to increase in volume of post. So is volume need to be calculated in factor loading. InDependent Variable dependent Variables reputation -------------------------------->Volume (based on the no. of posting) social interaction ties --------------------->Volume Anyway, when i load it, it give me a eigenvalue of 0.999 .....what to do about it.
