absBstdres: Block version of abs-stdres Absolute values of residuals of kernel regressions
of standardized x on standardized y, no control variables.
Description
1) Standardize the data to force mean zero and variance unity, 2) kernel
regress x on y, with the option `residuals = TRUE' and finally 3) compute
the absolute values of residuals.
Usage
absBstdres(x, y, blksiz = 10)
Arguments
x
vector of data on the dependent variable
y
data on the regressors which can be a matrix
blksiz
block size, default=10, if chosen blksiz >n, where n=rows in matrix
then blksiz=n. That is, no blocking is done
Value
Absolute values of kernel regression residuals are returned after
standardizing the data on both sides so that the magnitudes of residuals are
comparable between regression of x on y on the one hand and regression of y
on x on the other.
Details
The first argument is assumed to be the dependent variable. If
abs_stdres(x,y) is used, you are regressing x on y (not the usual y
on x). The regressors can be a matrix with 2 or more columns. The missing values
are suitably ignored by the standardization.
