Hi,
i am working with xtfrontier using sectoral level
data.  xtfrontier is follwing battese coelli(1992)
time varying parameterisation and hence technical
efficiency effects can be calculated using this
command.
i also want to calculate technical progress to compose
total factor productivity.  can anyone help , how can
we do it. in their book 'an introduction to efficiency
and productivity analysis' tim coelli and  George
Battese, have mentioned that this can be done from the
parameters of stocahstic frontier produciton function
but i am not clear  what is the procedure?
Can anyone guide in this matter please.

Thank you
Naveeda
