# Model
|
||||
|
||||
The goal of a fitted model is to provide a simple low-dimensional summary of a dataset. Ideally, the fitted model will capture true "signals" (i.e. patterns generated by the phenomenon of interest), and ignore "noise" (i.e. random variation that you're not interested in).

You can organize tabular data in many ways. For example, the datasets below show the same data organized in four different ways. Each dataset shows the same values of four variables *country*, *year*, *population*, and *cases*, but each dataset organizes the values into a different layout . You can access the datasets in tidyr.

```{r}
|
||||
# Data set one
|
||||
# dataset one
|
||||
table1
|
||||
|
||||
# Data set two
|
||||
# dataset two
|
||||
table2
|
||||
|
||||
# Data set three
|
||||
# dataset three
|
||||
table3
|
||||
```
|
||||
|
||||
The last dataset is a collection of two tables.
|
||||
|
||||
```{r}
|
||||
# Data set four
|
||||
# dataset four
|
||||
table4 # cases
|
||||
table5 # population
|

```
