Claim:
A method for computing a correlation coefficient for a pair of occupations as an indication of transferability of workers between the occupations comprising: providing a computer to perform computations; selecting the pair of occupations; for each occupation in a set of occupations: entering into a matrix or database a set of scores for a selected individual worker attribute for an occupation, the set of scores for each attribute being one or more sets S k consisting of N k scores, where S k x j (j=1, 2, . . . N k ); computing, with the computer, a product of an importance score and a level score for the attribute to produce a composite attribute value; entering the composite attribute value into the matrix; accessing, with the computer, data in the matrix; computing, with the computer, a correlation coefficient for the pair of occupations by correlating the composite attribute value for the pair of occupations by the following formula: Correl ⁡ ( X , Y ) = ∑ i N k ⁢ ⁢ { ( x i - μ x ) ⁢ ( y i - μ y ) } [ ∑ i N k ⁢ ⁢ ( x i - μ x ) 2 ⁢ ∑ i N k ⁢ ⁢ ( y i - μ y ) 2 ] wherein: X and Y represent two vectors in a set, S k , of scores for the x th and y th occupations in a set of occupations; where both x and y run from 1 to N, where N is the number of occupations in the set of occupations and x and y are composite attribute values assigned to each occupation; k is a value indicating a level assigned to an individual worker attribute; x i a X; y i a Y; i=1, 2, . . . N k ; μ x = ∑ i N k ⁢ ⁢ { x i } N k is the mean value of the X vector and μ xy = ∑ i N k ⁢ ⁢ { y i } N k is the mean value of the Y vector; normalizing the correlation coefficients on a scale of 1 to 100; adjusting the normalized correlation coefficients by producing a ratio whereof the numerator is calculated as the sum of the differences between the members of each pair of the composite level-importance scores for two selected occupations, the two selected occupations being a source occupation and a destination occupation, for which the composite level-importance scores for the destination occupation exceed the composite level-importance scores for the source occupation, and the denominator is calculated as the raw sum of the composite level-importance scores of the destination occupation; and adjusting the correlation coefficients, with the computer, for each composite attribute by averaging it with the produced ratios; and producing a report of the correlation coefficients for all pairs of occupations in the set to indicate transferability of workers, indicated by a value of the correlation coefficients, between the occupations.
