error_lphom | R Documentation |
Estimation of the error index (EI) of a RxC vote transfer matrix obtained with lphom()
error_lphom( lphom.object, upper.alfa = 0.1, show.plot = TRUE, num.d = 11, B = 30 )
lphom.object |
An object output of the lphom() function. |
upper.alfa |
Upper bound that will not be exceed by the EI estimate with a confidence 1 - alpha. By default, 0.10. |
show.plot |
TRUE/FALSE. Indicates whether the plot showing the relationship between EI and HETe estimated by simulation for the election under study should be displayed as a side-effect. By default, TRUE. |
num.d |
Number maximum of different disturbances, |
B |
Integer that determines the number of simulations to be performed for each disturbance value. By default, 30. |
A list with the following components
EI.estimate |
Point estimate for EI. |
EI.upper |
Upper bound with confidence 1 - alpha of the EI estimate |
figure |
ggplot2 object describing the graphical representation of the relationship between EI and HETe. |
equation |
lm object of the adjustment between EI and HETe. |
statistics |
A four column matrix with the values of HET, HETe, EI and d associated with each simulated scenario. |
TMs.real |
Array with the simulated real transfer matrices associated with each scenario. |
TMs.estimate |
Array with the estimated transfer matrices associated with each scenario. |
ggplot2 is needed to be installed for this function to work.
See equation (12) in Romero et al. (2020) for a definition of the EI index.
