Applies the taut string method to binary data.
1 2 |
y |
observed values (ordered by value of independent variable) |
thr.const |
smoothing parameter for the multiresolution criterion (should be approximately 2.5) |
verbose |
logical, if T progress (for each iteration) is illustrated grahically |
extrema.nr |
if set to a positive integer an approximation with the specified number of local extreme values is calculated |
bandwidth |
if set to a positive value the specified bandwidth is used instead of the multiresolution criterion. |
localsqueezing |
logical, if T (default) the bandwidth is changed locally. |
squeezing.factor |
The amount of decrement applied to the bandwidthes |
tolerance |
Accuracy used for the determination of the bandwidth when extrema.nr is greater than 0. |
extrema.mean |
logical, if T (default) the value of the taut string approximation at local extreme values is set to the mean of the observations on the interval where the extremum is taken. |
A list with components
y |
The approximation of the given data |
widthes |
Bandwidth used |
nmax |
Number of local extreme values |
knotsind |
Indices of knot points |
knotsy |
y-koordinates of knots of the taut string |
