Methods

IconTypeDescription
DistributionFunction(Double)
Evaluates the cumulative distribution function (CDF) of this distribution for the specified value.
Equals(Object)
Determines whether the specified Object is equal to the current Object.
Finalize()
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
GetExpectedHistogram(Double[](), Double)
Gets a Histogram whose bins contain the expected number of samples for a given total number of samples.
GetExpectedHistogram(Double, Double, Int32, Double)
Gets a Histogram whose bins contain the expected number of samples for a given total number of samples.
GetHashCode()
Serves as a hash function for a particular type.
GetRandomVariate(Random)
Returns a random sample from the distribution.
GetRandomVariates(Random, Vector)
Fills a Vector with random numbers.
GetRandomVariates(Random, Double[]())
Fills a Double array with random numbers.
GetRandomVariates(Random, Double[](), Int32, Int32)
Fills a Double array with random numbers.
GetRandomVariates(Random, Vector, Int32, Int32)
Fills a Double array with random numbers.
GetType()
Gets the Type of the current instance.
InverseDistributionFunction(Double)
Returns the sample value at the specified percentile.
MemberwiseClone()
Creates a shallow copy of the current Object.
Probability(Double, Double)
Returns the probability that a sample taken from the distribution lies inside the specified interval.
ProbabilityDensityFunction(Double)
Returns the value of the probability density function (PDF) of this distribution for the specified value.
SurvivorDistributionFunction(Double)
Evaluates the survivor distribution function (SDF) of this distribution for the specified value.
ToString()
Returns a String that represents the current Object.

Constructors

IconTypeDescription
LognormalDistributionNew(Double, Double)
Constructs a new LognormalDistribution object with the specified location and scale parameters.
LognormalDistributionNew(NumericalVariable)
Estimates the parameters of the distribution of a variable assuming it follows a lognormal distribution.

Properties

IconTypeDescription
InterQuartileRange
Returns the inter-quartile range of this distribution.
IsSymmetrical
Gets a value that indicates whether the distribution is known to be symmetrical around the mean.
Kurtosis
Gets the kurtosis of the distribution.
LocationParameter
Gets the location parameter for the distribution.
Mean
Gets the mean or expectation value of the distribution.
ScaleParameter
Gets the scale parameter for the distribution.
Skewness
Gets the skewness of the distribution.
StandardDeviation
Gets the standard deviation of the distribution.
Variance
Gets the variance of the distribution.

Remarks

The logarithm of a variable with a normal distribution has a Log Normal distribution. The main parameters are those of the underlying NormalDistribution: mean, and standard deviation.
