[S] How to use this methods: Holt-Winters and Brown (Time Series Analysis)

[Fábio Feitosa Carvalho <fabiofc@peb.ufrj.br>]

Dear Fellows,

        I'm a pos-graduate student from Federal University of Rio de Janeiro
and I'm trying to use S-Plus to analise Time Series. I'm trying to locate on
s-plus help information about methods to:

               1) Exponencial smoothing models 
                        . Modelos de Médias Móveis Simples - "Simple Move
Averages"
                        . Alisamento Exponencial Simples - "Simple
Exponencial Smoothing"
                        . Alisamento Exponencial Biparamétrico de
Holt-Winters - "Holt-Winters Biparametric Exponential Smoothing")

               2) Methods to Modeling Sazonal Time Series
                        . Modelos de Alisamento Exponencial Sazonal de
Holt-Winters - "Holt-Winters Exponencial Sazonal Smoothing"
                        . Alisamento Exponencial Geral (Método de Brown) -
Geral Exponencial Smoothing (Brown's Method).

        Does anyone:

                1) Knows anything about this methods?
                2) Knows if S-plus can do a Time Series analysis using this
methods?
                3) Knows HOW TO DO or WHERE I CAN FIND INFORMATION about this?
                4) Knows where I can find a program (other) to do this?

        Thanks in Advance.
