Dear Sangeeta:
You can try our programs for testing the modality of univariate data:
STB-38 snp13 . Nonparametric assessment of multimodality for univariate data
(help warpdenm if installed) . . . . Salgado-Ugarte, Shimizu, Taniuchi
7/97 pp.27--35; STB Reprints Vol 7, pp.232--243
implementation of smoothed bootstrap procedure of Silverman for
multimodality assessment
With the ado-files included you can bootstrap kde's and later to count the
number of modes one by one interectivelly or automatically with the silvtest.ado
program and sending the result listing to a log file (to keep track of any
single result).
Hope this could help.
