Estimation of location and magnitudes of change in intercept and slope, for piecewise linear models.
fitS_linear(dataIn,xColIndex=NULL,yColIndex=NULL,plotTitle = '')
Object of class "fittedS_linear", with components:
The pre-changepoint slope.
The post-changepoint slope.
S-curve slope for finding regression slope.
The changepoint.
Pre-changepoint intercept.
Post-changepoint intercept.
S-curve slope for finding regression slope.
The gap at the changepoint is then
(h2 + h2 c) - (b2 + b1 c)
Data frame or equivalent.
Column number of "x" (typically time).
Column number of "y".
Title for output plot, if any.
