Laney P' chart is a new variant of the regular P chart.
The Laney P' chart is similar to a traditional P chart. Both charts monitor the proportion of defective items that are produced by your process. However, if your data exhibit overdispersion or underdispersion, a Laney P' chart may more accurately distinguish between common-cause variation and special-cause variation.
Minitab already has it but Statistica V13.5 does not.
Our first customer is already asking for this node. It would be great if we could enable this.
This not not about a single customer. I've seen requests in multiple presentations. Ticbo does not get hold of such information until now, because there is no channel of communication for not-yet-customers.
Good idea, I support the need of Laney P' chart in Statistica.
