cstari {cstar} | R Documentation |
cstari computes the minimum actionable effect size under a kinked linear loss function with user-specified degree of risk aversion. It computes this value from a beta, its associated standard error, and the degrees of freedom of a regression, and gamma, e.g. enables researchers to compute this quantity from a table of published results.
cstari(b, v, degfr, r)
b |
The beta of interest from a linear regression model. |
v |
The standard error associated with the beta of interest. |
degfr |
The degrees of freedom of the regression. |
r |
The degree of loss aversion; must be a non-negative number. This parameter maps to gamma in Esarey and Danneman (2014). |
The expected value for the utility of acting on the evidence encapsulated by the beta and standard error of the estimated regression, given the researcher's stated level of loss aversion.
