Find maximum, minimum, and median values for each scenario found using qi_builder
Description
Find maximum, minimum, and median values for each scenario found using
qi_builder
Usage
1 
Arguments
df 
a data frame of simulated quantities of interest created by

Details
This funciton slims down a simulation data set to some of its key features (minimun, median, and maximum value for each fitted scenario) so that it takes up less memory and can be easily plotted.
The function is incorporated into qi_builder
and can be run
using slim = TRUE
.
Value
A data frame with the fitted values and the minimum (qi_min
),
median (qi_median
), and maximum (qi_max
) values from the
central interval specified with ci
in qi_builder
.

# Normal linear model
m1 < lm(prestige ~ education + type, data = Prestige)
# Simulate coefficients
m1_sims < b_sim(m1)
# Create fitted values
fitted_df < expand.grid(education = 6:16, typewc = 1)
# Find predicted outcomes (95% central interval, by default)
linear_qi < qi_builder(b_sims = m1_sims, newdata = fitted_df, slim = FALSE)
# Slim data set
linear_slim < qi_slimmer(linear_qi)
