intercept | R Documentation |
Computes the intercepts of each ‘segmented’ relationship in the fitted model.
intercept(ogg, parm, rev.sgn = FALSE, var.diff=FALSE,
.vcov=NULL, .coef=NULL, digits = max(4, getOption("digits") - 2),...)
ogg |
an object of class "segmented", returned by any |
parm |
the segmented variable whose intercepts have to be computed. If missing all the segmented variables in the model are considered. |
rev.sgn |
vector of logicals. The length should be equal to the length of |
var.diff |
Currently ignored as only point estimates are computed. |
.vcov |
The full covariance matrix of estimates. If unspecified (i.e. |
.coef |
The regression parameter estimates. If unspecified (i.e. |
digits |
controls number of digits in the returned output. |

A broken-line relationship means that a regression equation exists in the intervals
'min(x)
to \psi_1
', '\psi_1
to \psi_2
', and so on.
intercept
computes point estimates of the intercepts of the different regression equations
for each segmented relationship in the fitted model.
intercept
returns a list of one-column matrices. Each matrix represents a segmented relationship.

to compute the slopes of the different regression equations
for each segmented relationship in the fitted model.
