inverse transformation and reflection

#1
Hi all,

I'm doing a multiple regression analysis and my outcome variable is strongly positively skewed.
Without transformation skewness = 2.10 and kurtosis = 5.11 and the Q-Q plot looks bad
with a log-transformation skewness = 1.44 and kurtosis = 1.67 and the Q-Q plot looks better but still not very good
An inverse transformation gives skewness=.99 and kurtosis=-.01 and now the Q-Q plot looks much better as do the residuals after the regression. Thus I want to use the inverse transformation.

My question:
the original range of the variable is 5-14 and with the inverse transformation it becomes
.07 - .20
However the sign of the regression coefficient changes so I want to reverse the distribution, how is this correctly done? Can I do it after the inverse transformaion by multiplying with -1 and adding 1.20 ?

Thanks, Annette
