Composition function for use in
sample_lef. Given a count of
the number of threat events (TEF) and the level of vulnerability (as a
percentage), calculate how many of those become loss events (LEF).
compare_tef_vuln(tef, vuln, n = NULL)
Threat event frequency (n).
Number of samples to generate.
List containing samples (as a vector) and details (as a list).
compare_tef_vuln(tef = 500, vuln = .25)#> $samples #>  125 #> #> $details #> list() #>
