1 2 |
y |
the response vector of length n where n is the total of observations. |
X |
the matrix of explanatory variables of dimension n x (p+1) where n is the total of observations and p is the number of variables. |
family |
its defines the distribution to ber used: sn, stn, ssl, scn or sep. |
method |
the method to calculate the maximum likelihood estimates: EM algorithm or direct maximum likelihood estimates via Newton-Raphson. |
maxit |
Maximum number of iterations. |
error |
accuracy the convergence maximum error. |
show.envelope |
TRUE or FALSE. Indicates if envelope graph should be built for the fitted model. Default is FALSE. |
alpha |
1 - alpha is level of confidence. |
theta |
Estimated parameter vector |
The function returns a list with 8 elements detailed as
iter |
number of iterations. |
tetha |
estimated parameter vector. |

AIC |
Akaike information criterion. |
BIC |
Bayesian information criterion. |
