\[ \mu_{x} = GM(r,s) = \alpha_{1} + \alpha_{2} t + \dots \]
where t is linear function of x.
However, \( t = c^x \) is not a linear function. So, where am I wrong?
N.B. I substitute \( t = c^x \) into equation to get:
\[ \mu_{x} = GM( r,s ) = \alpha_{2} c^x + \dots Gompertz \]
\[ \mu_{x} = GM( r,s ) = \alpha_{1} + \alpha_{2} c^x + \dots Makeham\]
