More formally, if [theta] is a scaling parameter and w is a measure of wealth, the inverse hyperbolic sine of wealth can be written as [[theta].
The pattern of coefficients from the inverse hyperbolic sine specification, shown in table 3, is similar.
In the inverse hyperbolic sine decompositions, nearly all of the net worth increase in all three age groups can be attributed to changes in demographic variables.
Only two coefficients change in a consistent and statistically significant manner across specifications and age groups: One is the "female, postsecondary education" coefficient, which is larger in 2001 than in 1989 for the 45-54 group in both specifications, and smaller in 2001 than in 1989 for the 75-84 group in the levels specification and for the 65-74 and 75-84 groups in the inverse hyperbolic sine specification; the other is the "years since divorce or death of spouse" coefficient, which is smaller in 2001 than in 1989 in the levels specification for all three younger age groups and in the inverse hyperbolic sine specification for the 25-34 group.
