temp_situations {decisionSupport}

Situation occurrence and resolution

Description

This function simulates a situation, e.g. a conflict, that arises with a certain probability, generates an impact as long as it persists, and has a certain chance of being resolved.

Usage

temp_situations(
  n,
  p_occurrence,
  p_resolution,
  normal_outcome = 1,
  situation_outcome = 0,
  var_CV_normal = 0,
  var_CV_situation = 0
)

Arguments

n

integer; number of values to produce

p_occurrence

chance that a situation (e.g. conflict) occurs (probability btw. 0 and 1)

p_resolution

chance that the situation disappears (e.g. the conflict gets resolved) (probability btw. 0 and 1)

normal_outcome

output value for vector elements that aren't affected by the situation (can be subject to random variation, if var_CV_normal is specified). Defaults to 1.

situation_outcome

output value for vector elements that are affected by the situation (can be subject to random variation, if var_CV_situation is specified). Defaults to 0.

var_CV_normal

desired coefficient of variation for 'normal' vector elements (in percent). Defaults to 0.

var_CV_situation

desired coefficient of variation for elements of the vector that are affected by the situation (in percent). Defaults to 0.

Value

vector of n numeric values, representing a variable time series, which simulates the effects of a situation that arises with a probability p_occurrence and disappears again with a probability p_resolution
