_cast_to_stata_types(data: 'DataFrame') -> 'DataFrame'
Numeric columns in Stata must be one of int8, int16, int32, float32 or float64, with some additional value restrictions. int8 and int16 columns are checked for violations of the value restrictions and upcast if needed. int64 data is not usable in Stata, and so it is downcast to int32 whenever the value are in the int32 range, and sidecast to float64 when larger than this range. If the int64 values are outside of the range of those perfectly representable as float64 values, a warning is raised.
bool columns are cast to int8. uint columns are converted to int of the same size if there is no loss in precision, otherwise are upcast to a larger type. uint64 is currently not supported since it is concerted to object in a DataFrame.
The DataFrame to check and convert
Checks the dtypes of the columns of a pandas DataFrame for compatibility with the data types and ranges supported by Stata, and converts if necessary.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
