Description
Gives a graphical representation of the Bradley's scores.
Usage
Piplot(Pi, SigmaPi = NULL, level=0.05, main = NULL, ylab = "Bradley's scores",
xlab = "Item", labelprod = NULL)
Arguments
Pi |
vector of Bradley's scores |
SigmaPi |
vector of Bradley's scores standard deviation given by the user. |
level |
level to use for the confidence intervals. (default |
main |
Title of the plot.(default |
ylab |
value for |
xlab |
value for |
labelprod |
label vector of the Item. (default |
Details
The representation is based on plot(x) function, with Item on x axis, and Bradley's scores on y axis. If SigmaPi
is provided by user, a 1-level
(default 95%) confidence interval is drawn for each Item.
Value
A graphical representation of bradley's scores.
Examples
data(Cocktail_Cum)
res<-C_piBTL(Cocktail_Cum,Constraint=0,eps1=0.0001,Pi=NULL,TestPi=TRUE)
Res_Pi<-res$Pi
Res_Varcov<-res$VarcovPi
Res_Sigma<-sqrt(diag(Res_Varcov))
Piplot(Res_Pi, SigmaPi = Res_Sigma, level=0.01, main = NULL, ylab = "Bradley's scores",
xlab = "Item", labelprod = NULL)
