## Money Demand

### Description

Money Demand Data.

### Usage

`data(moneydemand)`

### Format

A multivariate yearly time series from 1879 to 1974 with variables

logM

logarithm of quantity of money,

logYp

logarithm of real permanent income,

Rs

short term interest rate,

Rm

rate of return on money,

Rl

not documented in the sources,

logSpp

logarithm of an operational measure of the variability of the rate of price changes.

### Source

The data was originally studied by Allen (1982), the data set is given in Krämer and Sonnberger (1986). Below we replicate a few examples from the book. Some of these results differ more or less seriously and are sometimes parameterized differently.

### Examples

```data(moneydemand)
moneydemand <- window(moneydemand, start=1880, end=1972)

## page 125, fit Allen OLS model (and Durbin-Watson test),
## last line in Table 6.1

modelAllen <- logM ~ logYp + Rs + Rl + logSpp
lm(modelAllen, data = moneydemand)
dwtest(modelAllen, data = moneydemand)

## page 127, fit test statistics in Table 6.1 c)

## Breusch-Pagan
bptest(modelAllen, studentize = FALSE, data = moneydemand)
bptest(modelAllen, studentize = TRUE, data = moneydemand)

## RESET
reset(modelAllen, data = moneydemand)
reset(modelAllen, power = 2, type = "regressor", data = moneydemand)
reset(modelAllen, type = "princomp", data = moneydemand)

## Harvey-Collier tests (up to sign of the test statistic)
harvtest(modelAllen, order.by = ~logYp, data = moneydemand)
harvtest(modelAllen, order.by = ~Rs, data = moneydemand)
harvtest(modelAllen, order.by = ~Rl, data = moneydemand)
harvtest(modelAllen, order.by = ~logSpp, data = moneydemand)

## Rainbow test
raintest(modelAllen, order.by = "mahalanobis", data = moneydemand)

if(require(strucchange, quietly = TRUE)) {
## Chow (1913)
sctest(modelAllen, point=c(1913,1), data = moneydemand, type = "Chow") }

if(require(strucchange, quietly = TRUE)) {
## Fluctuation
sctest(modelAllen, type = "fluctuation", rescale = FALSE, data = moneydemand)}
