par2list function

Transfer a vector into a list

par2list(par, g, p, ncov = 2, type = c("ign", "full"))

Arguments

• par: A vector with list information.
• g: Number of multivariate normal classes.
• p: Dimension of observation vecor.
• ncov: Options of structure of sigma matrix; the default value is 2; ncov = 1 for a common covariance matrix that sigma is a $p\times p$ matrix. ncov = 2 for the unequal covariance/scale matrices that sigma represents a list of g matrices with dimension $p\times p \times g$.
• type: Three types to fit to the model, 'ign' indicates fitting the model on the basis of the likelihood that ignores the missing label mechanism, 'full' indicates that the model to be fitted on the basis of the full likelihood, taking into account the missing-label mechanism, and 'com' indicate that the model to be fitted to a completed classified sample.

Returns

• parlist: Return a list including mu, pi, sigma and xi.
