楼主在进行非线性回归,因为expression too long引起问题,所以楼主转用了nl的function evaluator program(FEP)功能。
但是FEP现在出现一个r(111)的问题,具体报错信息就只有如下
nlcombination returned 111
verify that nlcombination is a function evaluator program
我也在google中查找了基本上所有关于这个问题的解答也还是找不出答案,所以请教下这种具体报错信息只有两句,没有具体问题的错误怎么解决。下面是r(111)的问题解释,我一一对应着找了,不存在变量没有定义以及merge或者缩写的问题,至于variable out of order我的varlist中也没有varname1-varname2的定义,所以有碰到相同问题的朋友吗,或者某位大神帮忙解答下
r(111)“ error . . . . . . . . . . . . . . . . . . . . . . . . Return code 111
__________ not found;
no variables defined;
The variable does not exist. You may have mistyped the
variable's name.
variables out of order;
You specified a varlist containing varname1-varname2, yet
varname1 occurs after varname2. Reverse the order of the
variables if you did not make some other typographical error.
Remember, varname1-varname2 is taken by Stata to mean varname1,
varname2, and all the variables in dataset order in between.
Type describe to see the order of the variables in your dataset.
__________ not found in using data;
You specified a varlist with merge, but the variables on which
you wish to merge are not found in the using dataset, so the
merge is not possible.
__________ ambiguous abbreviation;
You typed an ambiguous abbreviation for a variable in your data.
The abbreviation could refer to more than one variable. Use a
nonambiguous abbreviation, or if you intend all the variables
implied by the ambiguous abbreviation, append a `*' to the end
of the abbreviation.”
