curlin的PSTR的结果啊！就是不明白怎么计算产出弹性了！

*** FINAL ESTIMATION OF PSTR MODEL ***
**************************************

   Final Estimation of the Model with r = 1 and m = 1 by NLS ***

   Initial Conditions on (gamma,c) :
    4.8632   -1.4664

  RSS = 3.982      Convergence = 1   

  AIC = -5.221      BIC = -5.184   

Estimated slope parameter of the transition function (one for for each transition function)
    4.8632

Estimated location parameters (per column for each transition function)
   -1.4664

Estimated slope parameters (per column for each transition function)
    0.3460   -0.0974
    0.4430   -0.3796

Standard Errors of estimated slope parameters corrected fo heteroskedasticity (per column for each transition function)
    0.0234    0.0199
    0.0352    0.0342

t-statistics based on corrected standard errors (per column for each transition function)
   14.8021   -4.9051
   12.5958  -11.1053

OUPUT: Individual Elasticities for each explicative variable (first column is the cross section identifier) are available in the excel file result1.xls
