draw.weibull {UnivRNG} | R Documentation |
This function implements pseudo-random number generation for a Weibull distribution with pdf
f(x|\alpha,\beta)=\frac{\alpha}{\beta^{\alpha}}x^{\alpha-1}e^{-(x/\beta)^{\alpha}}
for 0 \leq x < \infty
and \min(\alpha,\beta)>0
where \alpha
and \beta
are the shape and scale parameters, respectively.
draw.weibull(nrep, alpha, beta)
nrep |
Number of data points to generate. |
alpha |
Shape parameter of the desired Weibull distribution. |
beta |
Scale parameter of the desired Weibull distribution. |
A list of length five containing generated data, the theoretical mean, the empirical mean, the theoretical variance, and the empirical variance with names y, theo.mean, emp.mean, theo.var, and emp.var, respectively.
