Approximation

Constant

$FT{G}_a^z=n_a^z\cdot K^a$

Linear

$FT{G}_a^z=n_a^z\cdot \left(K^a+a^a\cdot \overline{Em{p}_a^z}\right)$

Logarithmic

$FT{G}_a^z=n\cdot a^a+b^a\cdot n_a^z\cdot \log \left(\overline{\overline{Em{p}_a^z}}\right)$

$FT{G}_a^z{}^{*}=n\cdot a^a+b^a\cdot n_a^z\cdot \log \left(\overline{Em{p}_a^z}\right)$

Potential

$FT{G}_a^z=a^a\cdot n_a^z\cdot {\left(M_{b^a}\left(Em{p}_a^z\right)\right)}^{b^a}$

$FT{G}_a^z{}^{*}=a^a\cdot n_a^z\cdot {\left(\overline{Em{p}_a^z}\right)}^{b^a}$
