Title: Optimal Experimental Designs for Accelerated Life Testing
Authors@R: c(person("Kangwon", "Seo", role = c("aut", "cre"),
Description: This package creates the optimal (D, U and I) designs for
the accelerated life testing with right censoring or interval censoring.
It uses generalized linear model (GLM) approach to derive the asymptotic
variance-covariance matrix of regression coefficients. The failure time
distribution is assumed to follow Weibull distribution with a known shape
parameter and log-linear link functions are used to model the relationship
between failure time parameters and stress variables. Any number of stress
factors can be used but no more than 3 are recommended due to the
computational time. ALTopt package also provides several plotting functions
including contour plot, Fraction of Use Space (FUS) plot and Variance
Dispersion graphs of Use Space (VDUS) plot.
