The formula "(NS1U1B1ColumnsS1U1B0-1)(NS1U1B1RowsS1U1B0-1)" is used to calculate the degrees of freedom for the chi-square test for independence, where NS1U1B1Columns is the number of columns in the contingency table and NS1U1B1Rows is the number of rows in the contingency table. This formula gives the total number of degrees of freedom for the test.
