ModelNMoE-class: A Reference Class which represents a fitted NMoE model.

Description

ModelNMoE represents an estimated NMoE model.

Fields

param

A ParamNMoE object. It contains the estimated values of the parameters.

stat

A StatNMoE object. It contains all the statistics associated to the NMoE model.

Methods

plot(what = c("meancurve", "confregions", "clusters", "loglikelihood"), ...)

Plot method.

what

The type of graph requested:

• "meancurve" = Estimated mean and estimated experts means given the input X (fields Ey and Ey_k of class StatNMoE).

• "confregions" = Estimated mean and confidence regions. Confidence regions are computed as plus and minus twice the estimated standard deviation (the squarre root of the field Vary of class StatNMoE).

• "clusters" = Estimated experts means (field Ey_k) and hard partition (field klas of class StatNMoE).

• "loglikelihood" = Value of the log-likelihood for each iteration (field stored_loglik of class StatNMoE).

…

Other graphics parameters.

By default, all the graphs mentioned above are produced.

summary(digits = getOption("digits"))

Summary method.

digits

The number of significant digits to use when printing.

Examples

# NOT RUN {
data(tempanomalies)
x <- tempanomalies$Year
y <- tempanomalies$AnnualAnomaly

nmoe <- emNMoE(X = x, Y = y, K = 2, p = 1, verbose = TRUE)

# nmoe is a ModelNMoE object. It contains some methods such as 'summary' and 'plot'
nmoe$summary()
nmoe$plot()

# nmoe has also two fields, stat and param which are reference classes as well

# Log-likelihood:
nmoe$stat$loglik

# Parameters of the polynomial regressions:
nmoe$param$beta
