In broad terms, considering the explanatory power of a factor, we retain the factors with eigenvalue more than 1 as a

common factor, consistent with the first five factors.

The fact that it takes a larger number of

common factors for the IFE elasticity estimate based on CPS ORG data to become small is consistent with the result in Table 6 that it takes a larger number of

common factors to explain the variation in the CPS ORG residuals; it takes four factors to explain roughly the same fraction of the variation in the CPS ORG residuals that is explained by the first

common factor for restaurant employment.

Previous studies about

common factors are almost empirical ones, and main purposes of these researches are identifying

common factors with explanatory power for dynamics of stocks, such as momentum factor [19], short-term reversal factor [20], long-term reversal factor [3], and liquidity factor [21].

Therefore, the commonality is the sum square of the coefficients or factor loadings of the

common factors. The common variance [h.sup.2.sub.i] reflects the explained extent of the

common factor to the total variance of the variables.

In terms of data mining methodology, in EFA each variable or

common factor has only one chance to be included in a single category, which means multiple correspondence between variables and categories cannot be created.

For the students, it could be noted that the coefficients of a and b in the sequence [t.sub.n] are successive Fibonacci numbers and they seem never to have

common factors.

Talking to Gulf News about the findings, which was first reported by Arabic daily Emarat Al Youm, Dr Manal said smoking medwakh was the one

common factor among all the patients (aged between 20 to 40), in whose urine traces of marijuana were found.

Clare Fear, defending Williams, said substance misuse had been a "very

common factor" in his life.

BarraOne is a global, multi-asset platform for total plan risk and performance, providing multiple views of risk, including

common factor, stress testing, value at risk and sensitivity-based analytics.

Another

common factor, is that both cities have had their share of tragedies.

Speed is a

common factor. These leather loonies ride at terrifying speeds.
