Power supplier multi-dimensional data null value assignment method, system, device and terminal

The invention belongs to the technical field of data processing, and discloses a power supplier multi-dimensional data null value assignment method, system, device and terminal, and the method comprises the steps: inputting supplier multi-dimensional basic data; dividing the data into a basic data set and a multi-null data set according to the null rate of each data dimension; each supplier data null value in each column of the multi-null-value data set is calculated for the basic data, comparison and analysis are carried out by utilizing the industry change factors, and value assignment is carried out on the multi-null-value data set; the multi-empty data set serves as a basic data set, the basic data set serves as a multi-empty data set, and assignment of the basic data set is completed; and combining the basic data set and the porous data set, and outputting the assigned data set. Compared with a traditional multi-dimensional data null value assignment method, the power supplier multi-dimensional data null
