supplied_quantities(object, parameters)

Arguments

object

A model object.

parameters

A vector of model's parameters.

Examples

# NOT RUN {
# initialize the model using the houses dataset
model <- new(
  "diseq_basic", # model type
  c("ID", "TREND"), "HS", "RM", # keys, quantity, and price variables
  "RM + TREND + W + CSHS + L1RM + L2RM + MONTH", # demand specification
  "RM + TREND + W + L1RM + MA6DSF + MA3DHF + MONTH", # supply specification
  fair_houses(), # data
  correlated_shocks = FALSE # allow shocks to be correlated
)

# estimate the model object (BFGS is used by default)
est <- estimate(model)

# get estimated demanded and supplied quantities
head(cbind(demanded_quantities(model, est@coef),
     supplied_quantities(model, est@coef)))
# }
