Examples
Shows how to calculate statistic of risks.
var settings = new RiskAnalysisSettings
{

};
var project = new Project(DataDir + "Software Development Plan-1.mpp");
var task = project.RootTask.Children.GetById(17);
// Initialize a risk pattern
var pattern = new RiskPattern(task)
{
// Select a distribution type for the random number generator to generate possible values from (only two types currently supported, namely normal and uniform)
// For more details see here: https://en.wikipedia.org/wiki/Normal_distribution)
Distribution = ProbabilityDistributionType.Normal,
// Set the percentage of the most likely task duration which can happen in the best possible project scenario
// The default value is 75, which means that if the estimated specified task duration is 4 days then the optimistic duration will be 3 days
Optimistic = 70,
// Set the percentage of the most likely task duration which can happen in the worst possible project scenario
// The default value is 125, which means that if the estimated specified task duration is 4 days then the pessimistic duration will be 5 days.
Pessimistic = 130,
// Set a confidence level that correspond to the percentage of the time the actual values will be within optimistic and pessimistic estimates.
// You can think of it as a value of standard deviation: the more uncertain about your estimates you are, the more the value of standard deviation used in random number generator is
ConfidenceLevel = ConfidenceLevel.CL75

// Analyze the project risks
var analyzer = new RiskAnalyzer(settings);
