WebThe factor analysis model requires k(m+1) elements; i.e. the number of parameters in L (namely km) plus the number of elements in X = μ + LY + ε (namely k). Thus, we desire a value for m such that k(m+1) ≤ k(k+1)/2, i.e. m ≤ (k–1)/2. For Example 1 of Factor Extraction, we are looking for m ≤ (k–1)/2 = (9–1)/2 = 4. Our preference ...
