总共做了15次回归，先前的回归都保存了每次回归所有的信息

执行下面命令时

esttab m1 m2 m3 m4 m5 m6 m7 m8 m9 m10 m11 m12 m13 m14 m15 using Table1.csv,append
compress nogap b(%6.3f) p(%6.3f) scalar(N r2 F r2_a) compress
star(* 0.1 ** 0.05 *** 0.01)
mtitles(1 2 3 4 5 6 7 8 9 10 11 12 13 14 15)


显示：

matsize too small
    You have attempted to create a matrix with too many rows or columns or attempted to fit a model with too many variables.       You need to increase matsize; it is currently 400.  Use set matsize; see help matsize.


    If you are using factor variables and included an interaction that has lots of missing cells, either increase matsize or set           emptycells drop to reduce the required matrix size; see help set emptycells.


    If you are using factor variables, you might have accidentally treated a continuous variable as a categorical, resulting in lots of categories.  Use the c. operator on such variables.


r(908);


end of do-file


r(908);



随即修改命令：


set matsize 5000
esttab m1 m2 m3 m4 m5 m6 m7 m8 m9 m10 m11 m12 m13 m14 m15 using Table1.csv,append
compress nogap b(%6.3f) p(%6.3f) scalar(N r2 F r2_a) compress
star(* 0.1 ** 0.05 *** 0.01)
mtitles(1 2 3 4 5 6 7 8 9 10 11 12 13 14 15)


运行结果显示：

varlist not allowed
r(101);


end of do-file


r(101);


请问这是什么原因啊？在此先谢过啦^_^
