STATA do file for technical efficiency and elasticity of substitution analysis

I am using a panel data set for the manufacturing industries (firm-level data) for about 30 years, which includes 4 inputs (Capital, labour, energy and materials) and 1 output (manufacturing value added). I am going to use a stochastic frontier analysis (Translog input distance function approach) to calculate the elasticity of substitution (between factors of production) and technical efficiency (time-varying model preferably with half normal / truncated normal distribution) using the Maximum likelihood estimation (MLE). I wish to seek some help regarding formulating my STATA do-file for the project analysis. My key objectives include: 1. Translog input distance function need to be formulated basis Coelli and Perelman (1995,1999) 2. Technical efficiency needs to calculated basis Battese and Coelli (1992,1995) and further determinants of the technical efficiency also need to be evaluated basis a second stage regression. 3. The elasticity of substitution need to be calculated for multi-input case (basis Blackorby and Russell, 1989), i.e. Allen elasticity of substitution (AES), Morishima elasticity of substitution (MES), and the shadow elasticity of substitution (SES) 4. The direction of the causality of the relationship between technical efficiency and the elasticity of substitution need to be evaluated. The direction of this auxiliary regression will suggest as to whether technical efficiency is impacted by the elasticity of substitution or vice versa? 5. With my final objective is to seek the responsiveness of elasticity of substitution and technical efficiency (i.e. both separately) with respect to the varying firm sizes (in terms of employee headcount) and sub-sectoral classification (NAICS-4 level i.e. focussing on the sub-sectors of the food manufacturing industry) of the manufacturing industry. If more information desired then please contact.
