Hello! I have a question regarding WLS method for panel data. Could you please help me to understand whether I could use the coefficients of WLS model in order to interpret original data? Or it will be incorrect, because these coefficients relate to the weighted data? Thank you.

Good,.... but where is support of different input text file format??? Like: -1.00000000e-02 -8.31732036e+00 -9.90000000e-03 -8.31688757e+00 -9.80000000e-03 -8.31644855e+00 ... I just need to see graph and all. Looks like import this file is not easy.
