qqtrunc: QQ Plot for a Truncated Random Variable

Description

This function produces a QQ plot of sample quantiles against theoretical quantiles for a truncated random variable.

Usage

qqtrunc(x, spec, a = -Inf, b = Inf, title = "Truncated Distribution Q-Q Plot", xlabel = "Theoretical Quantiles", ylabel = "Sample Quantiles", ...)

a numeric vector of sample values
spec
a character value that specifies the underlying probability distribution
a

title
A character value for the chart title
xlabel
A character value for the horizon axis label
