unit_block_summary: Block Summary Function

In learningCurve: An Implementation of Crawford's and Wright's Learning Curve Production Functions

Description

Provides summary information for the block containing units m through n (where n > m). Based on Crawford's unit learning curve model.

Usage

unit_block_summary(t, m, n, r, na.rm = FALSE)

Arguments

t	time for the mth unit
m	lower bound unit of production block
n	upper bound unit of production block
r	learning curve rate
na.rm	Should NA values be removed?

Examples

# A production block runs from unit 201 to unit 500 inclusive.
# The 201st unit had a required time of 125 hours with a 75% 
# learning curve, what is the block summary?

unit_block_summary(t = 125, m = 201, n = 500, r = .75)
## $`block units`
## [1] 300

## $`block hours`
## [1] 30350.48

## $`midpoint unit`
## [1] 334.6103

## $`midpoint hours`
## [1] 101.1683
