cd3Model: Fit Cobb-Douglas models with 3 Factors

In EconModels/MacroGrowth: Economics Models

Description

Fit Cobb-Douglas models with 3 Factors

Usage

cd3Model(formula, data, response, x1, x2, x3, time, constrained = TRUE,
  save.data = TRUE, correlation = NULL, ...)

Arguments

formula	a formula of the form response ~ x1 + x2 + x3 + time
data	a data frame in which formala is evaluated
response	instead of specifying a formula, expressions for the components can be specified individually as character strings.
x1	instead of specifying a formula, expressions for the components can be specified individually as character strings.
x2	instead of specifying a formula, expressions for the components can be specified individually as character strings.
x3	instead of specifying a formula, expressions for the components can be specified individually as character strings.
time	instead of specifying a formula, expressions for the components can be specified individually as character strings.
constrained	a logical indicated whether the coefficents are constrained. See details
correlation	an optional nlme::corStruct object describing the within-group correlation structure. See the documentation of nlme::corClasses for a description of the available nlme::corStruct classes. If a grouping variable is to be used, it must be specified in the form argument to the nlme::corStruct constructor. Defaults to NULL, corresponding to uncorrelated errors.
...	additional arguments; currently unused.

Examples

data(EconUK)
cd3Model(response = iGDP, x1 = iK, x2 = iL, x3 = iQp, time = iYear, data = EconUK)
cd3Model(iGDP ~ iK + iL + iQp + iYear, data = EconUK)
cd3Model(response = "iGDP", x1="iK", x2="iL", x3="iQp", time="iYear", data = EconUK)
