Lower Control Limit: Binomial Data (p-chart)
Calculates point-wise lower control limit (LCL) for binomial proportion data acquired over a variable area of opportunity.
pBar_LCL(y, n, na.rm = FALSE, ...)
y |
Vector of binomial proportion data (not counts). Observations may have a different area of opportunity, n. |
n |
A vector representing the area of opportunity. |
na.rm |
a logical value indicating whether NA values should be stripped before the computation proceeds. |
... |
further arguments passed to or from other methods. |
A vector; point-wise 3-sigma lower control limit (LCL)
set.seed(5555) p <- rbinom(n = 100, size = 30, prob = .2) n <- rpois(100, 100) pBar_LCL(y = p/n, n = n)
