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. 

Isaías H. Salgado-Ugarte
