confidence_band
computes the lower and upper limits of smooth
terms fitted with intensity_pspline
.
confidence_band(theta, V, X, q = 0.05, R = 1000)
A list of two vectors which contain the lower and the upper limits of the confidence band.
The estimated coefficients which corresponds to the smooth term.
The covariance matrix of the estimated coefficients theta
.
The design matrix of the model which corresponds to the smooth term.
The quantile. Default to q = 0.05
which corresponds to
95% confidence bands.
The number of replications in the simulation process.
