slope_difference: slope_difference

In multipleITScontrol: Interrupted Time Series with a Control and Multiple Interventions

slope_difference

Description

Ascertains whether there is a statistically significant difference in a slope or level during an intervention period between the pilot group and the control group. The estimated difference is relative to the control group. I.e. a positive coefficient means the slope of the pilot group is higher than the control group.

The result is functionally equivalent to a two sided t-test.

Usage

slope_difference(model, intervention, return = TRUE)

Arguments

model	model output object from multipleITScontrol::fit_its_model
intervention	which intervention to test significance in difference. Integer value of 1, 2, or 3.
return	Logical for returning pretty output in console. TRUE by default

Value

A transformed data frame to be passed to transformed_df in fit_its_model.
