+ | |||
+ | For instance, a table might display concentrations of three contaminants, | ||
+ | |||
+ | ^Time^Nickel^Lead^Silver^ | ||
+ | ^0.0|1|2|3| | ||
+ | ^5.0|2|8|5| | ||
+ | ^...|...|...|...| | ||
+ | ^100.0|3|9|5| | ||
+ | |||
+ | by contaminants (rows) and contaminants (columns): | ||
+ | |||
+ | ^Time^0.0^5.0^...^100.0^ | ||
+ | ^Nickel|1|2|...|3| | ||
+ | ^Lead|2|8|...|9| | ||
+ | ^Silver|3|5|...|5| | ||
+ | |||
+ | If the data is probabilistic the dimension increase to three. With n=1000 iterations, the table would then become: | ||
+ | |||
+ | ^Time^Nickel/ | ||
+ | ^0.0|1|2|3|4|3|2|...|5|3|2| | ||
+ | ^5.0|2|8|5|2|6|1|...|8|6|8| | ||
+ | ^...|...|...|...|...|...|...|...|...|...|...| | ||
+ | ^100.0|3|9|5|6|2|4|...|9|6|5| | ||
+ | |||
+ | === Reduction === | ||
+ | |||
+ | For probabilistic data, it is more common to display statistics rather than data for each iteration. For example, by showing the mean and standard deviation the probabilistic dimension is reduced from thousands of items to just two: | ||
+ | |||
+ | ^Time^Nickel/ | ||
+ | ^0.0|3|1|3|7|9|4| | ||
+ | ^5.0|7|3|1|2|6|3| | ||
+ | ^...|...|...|...|...|...|...| | ||
+ | ^100.0|5|3|6|1|8|5| | ||
+ | |||
+ | The same can be done for time: instead of showing all time points, just show the first and last time point: | ||
+ | |||
+ | ^Time^Nickel/ | ||
+ | ^First|3|1|3|7|9|4| | ||
+ | ^Last|5|3|6|1|8|5| | ||
+ | |||
+ | If only the last time point is shown, the dimension of the data is reduced so that we can use rows for contaminants instead: | ||
+ | |||
+ | ^Contaminant^mean, | ||
+ | ^Nickel|5|1| | ||
+ | ^Lead|3|8| | ||
+ | ^Silver|6|5| | ||
+ | |||
+ | |||
+ | |||

+ | Depending on which view of the output data you seek there are different tables to choose from: | ||
* [[Time_table|Time table]] - Displays data for each time point. Useful for time dependent simulation outputs, like those from [[Compartment|compartments]]. | * [[Time_table|Time table]] - Displays data for each time point.
