If you want use unofficial octave-3.8.1, another way to install octave-forge 
packages exist.
I assume that default install directory (folder) structures are used.

>> cd C:\octave\Octave-3.8.1\src
>> build_packages

The packages installed by the build_packaes.m script are the following,
     actuarial *|   1.1.0
communications  |   1.2.0
       control *|   2.6.5
data-smoothing  |   1.3.0
       general  |   1.3.4
      geometry  |   1.7.0
         image  |   2.2.1
            io  |   2.2.2
linear-algebra  |   2.2.0
 miscellaneous  |   1.2.1
        odepkg *|   0.8.4
         optim  |   1.3.1
    quaternion *|   2.2.1
        signal  |   1.3.0
       sockets  |   1.0.8
       specfun  |   1.1.0
    statistics  |   1.2.3
        struct  |  1.0.10
       windows  |   1.2.1
        zenity  |   0.5.7

(The marks '*' after package names mean that the packages are activated and can 
be used. )

The statistics-1.2.3 will be installed.
If you want it auto-load, execute

>> pkg rebuild -auto io
>> pkg rebuild -auto statistics

The exit octave and restart octave.
And then to confirm they are active by:

>> pkg list

BTW, on windows 8 (8, 8.1,  8.1 update), it is necessary to start octave from 
batch file to execute it in GUI mode.
The batch file can be downloaded from 
http://wiki.octave.org/Octave_for_Microsoft_Windows#Octave_3.8_MXE_Builds

Click file name octave-gui.bat (blue colored), then you can download the batch 
file.
