Applies the taut string method to spectral densities.

x |
data |
pks |
if pks=0 then the number of peaks is determined
automatically. If pks = k >0 then a density with n paeks is returned |
alpha |
If pks=0 then on Gaussian test beds the number of peaks of the
true density is at least the returned value with an asymptotic
probability of at least alpha. If pks > 0 then the parameter is not
operational |
sqzf |
Squeeze factor for the taut string |
mult |
If mult = T then rescaled empirical density is compared
with the exponential distribution only on intervals forming a
multiresolution scheme. If T = F then all intervals are used. If the
sample size of the data is less than 512 then T = F is default |
lcl |
If lcl = T then string is calculated using local
squeezing. If lcl = F then global squeezing is used. |
fig |
If fig = T then the data are automticall plotted |
ln |
If fig = T and ln = T then the densities are plotted on a
log scale. If ln = F then no transformation is performed |
pow |
Peaks with a power less than pow * total power will be ignored |
edf |
Emprical spectral density |
df |
String density |
pks |
Number of peaks |
ll |
Lower boundary for string |
uu |
Upper boundary for string |
str |
