evalCDF
public double evalCDF(double t) Description copied from class:DistributionEvaluates the cumulative distribution function (CDF) at the given point.- Specified by:
evalCDFin classDistribution- Parameters:
t- the point at which to evaluate the CDF- Returns:
- the CDF value at point t
-
evalPMF
public double evalPMF(double t) - Overrides:
evalPMFin classDiscreteDistribution
-
evalLST
public double evalLST(double s) Evaluates the Laplace-Stieltjes Transform at s. For Geometric(p), LST(s) = p*e^(-s) / (1 - (1-p)*e^(-s))- Overrides:
evalLSTin classDiscreteDistribution- Parameters:
s- the Laplace domain variable- Returns:
- the LST value at s
-
getMean
public double getMean()Description copied from class:DistributionGets the mean (expected value) of this distribution.- Specified by:
getMeanin classDistribution- Returns:
- the mean value
-
getRate
public double getRate()Description copied from class:DistributionGets the rate of this distribution (inverse of mean).- Overrides:
getRatein classDistribution- Returns:
- the rate value (1/mean)
-
getSCV
public double getSCV()Description copied from class:DistributionGets the squared coefficient of variation (SCV) of this distribution. SCV = Var(X) / E[X]^2.- Specified by:
getSCVin classDistribution- Returns:
- the squared coefficient of variation
-
getSkewness
public double getSkewness()Description copied from class:DistributionGets the skewness of this distribution. Skewness measures the asymmetry of the probability distribution.- Specified by:
getSkewnessin classDistribution- Returns:
- the skewness value
-
getVar
public double getVar()Description copied from class:DistributionGets the variance of this distribution. Computed as SCV * mean^2.- Overrides:
getVarin classDistribution- Returns:
- the variance
-
sample
Gets n samples from the distribution- Specified by:
samplein classDistribution- Parameters:
n- - the number of samplesrandom- the random number generator to use- Returns:
- - n samples from the distribution
