Simple linear and nonparametric regression
simplereg(x, y, type = "lin", sp = NULL)
x |
numerical vector, input x values. |
y |
numerical vector, input y values. |
type |
character, type of regression; available options are: |
sp |
numeric, parameter to control the degree of smoothing; span for local polynomial regression and bandwidth for ksmooth. |
