bondyield: Bond Yield

Description

Bond Yield Data.

Usage

data(bondyield)

source

The data was originally studied by Cook and Hendershott (1978) and Yawitz and Marshall (1981), the data set is given in Kr�mer and Sonnberger (1986). Below we replicate a few examples given in their book. Some of these results differ more or less seriously and are sometimes parameterized differently.

Examples

data(bondyield)

## page 134, fit Cook-Hendershott OLS model and Yawitz-Marshall OLS model
## third and last line in Table 6.5

modelCH <- RAARUS ~ MOOD + EPI + EXP + RUS
lm(modelCH, data=bondyield)
dwtest(modelCH, data=bondyield)
## wrong sign of RUS coefficient

modelYM <- RAARUS ~ MOOD + Y + K
lm(modelYM, data=bondyield)
dwtest(modelYM, data=bondyield)
## coefficient of Y and K differ by factor 100
