i'm preparing a database to perform parameter learning in a bayesian network.
i built the network with genie.
Database is composed by some .dat tables
first i replaced missing values, then i don't understand why discretization option is disabled in some columns, as in some other no.
data are created with the decimal . not comma.
thanks for help

Re: discretization
There's no attachment in your post. Can you save your data file as .gdat, then zip it and post here?kiara_madrid wrote:i attached one table

Discretization works only for numeric columns.kiara_madrid wrote:here goes the dbase,
Columns like Ar_coef_2 or Freq_mh_ave contain non-numeric values (at least as far as GeNIe's text parser is concerned), like "5.711.776". Make sure your input file does not contain thousand separator.
Quick way to check which columns are considered numeric is to invoke the 'Statistics' dialog in GeNIe. The statistics are calculated only for numeric columns. Also, numeric columns are displayed right-aligned in the data grid.
