To compute the Purchasing Managers' Index

Calculate the unadjusted diffusion index for New Orders, Production, Employment, Inventories to two decimal places (percent higher or up plus one half of the percent same or unchanged). For Supplier Deliveries, it will be percent slower plus one half of the percent same or unchanged.
Divide each unadjusted diffusion index by its seasonal factor (round to one decimal place).
Multiply each seasonally adjusted diffusion index by its weight and sum. To compute other indexes, follow #1 and #2 above for each indicator.
