-The GLL-exponential model can be derived by setting  <math>m=L(\underline{X})</math>  in Eqn. (GLL1), yielding the following GLL-exponential  <math>pdf</math> :
-<br>
-<math>f(t,\underline{X})={{e}^{-\left( {{\alpha }_{0}}+\underset{j=1}{\overset{n}{\mathop{\sum }}}\,{{\alpha }_{j}}{{X}_{j}} \right)}}{{e}^{-\left( {{\alpha }_{0}}+\underset{j=1}{\overset{n}{\mathop{\sum }}}\,{{\alpha }_{j}}{{X}_{j}} \right)\cdot t}}</math>
-<br>
-The total number of unknowns to solve for in this model is  <math>n+1</math>  (i.e.  <math>{{a}_{0}},{{a}_{1}},...{{a}_{n}}).</math>
