用超越成本对数法进行成本效率分析，两个投入变量价格P1、P2，两项产出变量Y1，Y2，但输出结果为空，不知为什么，请高手指点，以下是数据和脚本文件。不知是变量计算不对，还是数据格式不对，亦或是脚本文件的问题，困惑！请高人答疑解惑。期待ing

NOTE: IF YOU ARE SUPPLYING STARTING VALUES
AND YOU HAVE RESTRICTED MU [OR DELTA0] TO BE
ZERO THEN YOU SHOULD NOT SUPPLY A STARTING
VALUE FOR THIS PARAMETER.
为清楚标识数据，这里加了一行数据说明，在分析时eg1.dta中是没有这一行的。
