Use to enter the total cost of repairs or number of repairs for each row of data. If you do not provide this column, Minitab assumes a cost of 1 for all failures. You must provide a cost/frequency column if you have grouped interval data.
Repair cost/number of repairs for systems: Enter a column containing the total cost of repairs or total frequency of repairs. The column must contain numeric values greater than or equal to 0. The value in this column must be 0 for a retired system. The first cost column is paired with the first data column, the second cost column is paired with the second data column, and so on.
