[hts-users:04283] Re: HMGenS output pdf sequences' format
Hi Najeeb,
I believe the values stored in HMGenS-generated pdf files do represent
a Gaussian distribution for each frame and window, but in the
"natural" (b-value, precision) parameterization rather than the (mean,
variance) parameterization. The b-value is mean-times-precision and
the precision is inverse variance. You should be able to easily check
this in the HMGenS.c source code.
