Lectura incorrecta de sigmaFixed en el noise de @Hierarchy

Reported by: mafernandez Owned by: mafernandez

Description

A la hora de crear el noise de una jerarquía el atributo:

Real _.sigmaFixed

controla si se quiere muestrear o no la varianza. En caso de que Real _.sigmaFixed = 1 la varianza no se muestrea sino que debería estar fija al valor que aparece en el atributo Real _.sigma.

Sin embargo, la capa import de jerarquía para ese caso no recoge _.sigma sino el valor inicial.

No hay tal error, me doy cuenta que al instanciar el noise de la jerarquía aparece:

Real initialSigma2 = getOptArg(args, "_.sigma", 1)^2;

Real noiseNormal::SetParameterSigma2([[
   Real _.initialValue = initialSigma2;
   Real _.isFixed = sigmaFixed
]]);

como se ve aparece _.initialValue como el (_.sigma)^2 . Luego es correcto como está. Ticket inválido.
