In his 1992 paper, (Psychological Assessment 1992, Vol.4, No. 2,145-155) Tellegen proposed a formula to calculate the uniform T score.
UT = B0 + B1X + B2X2 + B3X3.
B0 being the intercept, X the raw score and B1, B2 and B3 different regression coefficients. X2 is squared and X3 cubic.
What is the intercept ? How do you calculate the intercept (Bzero)?
How do you calculate the regression cofficient? Is it between the raw score and the percentile? Why 3 different regression coefficients?
Hi not sure if this helps, but this was the simplest explanation I found.

Yes the formula to obtain a linear T score is quite simple to apply. The question is more about uniform T score or normalized T score in order to address the sweness and kurtosis of different slopes.
