Examples

# Take data
D <- subset(Dbuilding, c("2010-12-15", "2011-01-01"))
D$y <- D$heatload
D$scoreperiod <- in_range("2010-12-20", D$t)
# Define a model
model <- forecastmodel$new()
model$add_inputs(Ta = "Ta",
                 mu = "one()")
model$add_regprm("rls_prm(lambda=0.99)")
model$kseq <- 1:6
# Fit it
fit <- rls_fit(prm=c(lambda=0.99), model, D)

# Get the forecasts (in fit$Yhat) on long format
long_format(fit)
