Optimal designs are used to determine the best conditions where an experiment should be performed to obtain certain statistical properties. In heteroscedastic nonlinear models where variance is a function of the mean, the optimality criterion depends

Resumen En la práctica pueden surgir complicaciones a la hora de construir diseños óptimos para modelos de regresión no lineales, uno de los grandes problemas se evidencia cuando las observaciones son correlacionadas, debido a que éstas son toma

The skew-normal (SN) distribution is a generalization of the normal distribution, where a shape parameter is added to adopt skewed forms. The SN distribution has some of the properties of a univariate normal distribution, which makes it very attracti
