ptrunc {truncdist} | R Documentation |
This function compute values of the cumulative distribution function for truncated random variables.
ptrunc(q, spec, a = -Inf, b = Inf, ...)
q |
a numeric vector of quantile values |
spec |
a character value that specifies the underlying probability distribution |
a |
a numeric value for the lower bound of the random variable |
b |
a numeric value for the upper bound of the random variable |
... |
other arguments are are passed to the corresponding quantile function |
A vector of probability values.
