In Minitab you can create designs and analyze data in amount, proportion, and pseudocomponent units.
To convert data from amount to proportion units, the formula is:
- Proportion = Amount / Total
If the total = 1, then the proportion units = amount units.
To convert proportion to pseudocomponent units, the formula is:
- Pseudo = (proportion - low) / (1 - sum of the lower bounds)
- Proportion = pseudo * (1 - sum of the lower bounds) + lower bound
If all lower bounds = 0, then pseudo units = proportion units
