The following equation was estimated using the data in CEOSAL$1$:

log$()=4\mathrm{.}322+0\mathrm{.}276$ log$()+0\mathrm{.}02150\mathrm{.}000082$

$(0\mathrm{.}324)(0\mathrm{.}033)(0\mathrm{.}0129)(0\mathrm{.}00026)$

n $=209,$ R$2=0\mathrm{.}282.$

This equation allows roe to have a diminishing effect on log$($salary$).$ Is this generality

necessary? Explain why or why not.
