请问楼主扩大面板纬度的时候有遇到这个问题吗,怎么办呀。
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 80. 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.
