fit_scenarios: Fit SME scenario estimates to distribution parameters

Description

Given a set of subject matter expert estimates for the 5th and 95th quantiles of impact and frequency of contact for events, calculate the distribution parameters for TEF and LM. Use a truncated lognormal distribution for LM (losses cannot be infinite in size) and for the TEF.

Usage

fit_scenarios(
  responses,
  maximum_impact = Inf,
  maximum_impact_factor = 10,
  maximum_frequency_factor = 10
)

Arguments

responses

A tidyrisk_response_set object.

maximum_impact

The absolute maximum potential impact of any single loss event.

maximum_impact_factor

Maximum impact factor - scaling factor of a SME's 95 percent maximum loss to limit the impact of any single event.

maximum_frequency_factor

Maximum frequency factor - scaling factor at which to limit frequency of events.

Value

A dataframe.
