how do I access likelihood distributions for Life Distributions?I would like to gain access to likelihood distributions for reliability life distributions, for example defective subpopulation weibull. specifically I would like to run a monte carlo on a function of the distribution parameters alpha, beta and p. Thanks in advance.
Re: how do I access likelihood distributions for Life Distributions?If you want to access the distribution functions for the purpose of a simulation, see Help > Scripting Index > Functions > Probability. The PDF, CDF, and ICDF are available for the common reliability life distribution models.
Re: how do I access likelihood distributions for Life Distributions?Are you talking about accessing these values through JSL?
If so, here's a script that will show you an example of how to extract those values:
//Create Data Table with random lognormal data
dt = New Table("Example Data");
dt << New Column("X",formula(random log normal()));
dt << Add Rows(300);
//Expression to fit Life Distribution with Log Normal fit & get parameter estimates
fit_and_get = Expr(
LD = dt << Life Distribution(
Y( :X ),
<<FIT lognormal=""></FIT>If you run it and look at the log, you'll see 5 different sets of parameter estimates and loglikelihood values
