statsmodels.graphics.gofplots.ProbPlot.probplot¶
- ProbPlot.probplot(xlabel=None, ylabel=None, line=None, exceed=False, ax=None, **plotkwargs)[source]¶
Plot of unscaled quantiles of x against the prob of a distribution.
The x-axis is scaled linearly with the quantiles, but the probabilities are used to label the axis.
- Parameters
- xlabel{
None
,str
},optional
User-provided labels for the x-axis. If None (default), other values are used depending on the status of the kwarg other.
- ylabel{
None
,str
},optional
User-provided labels for the y-axis. If None (default), other values are used depending on the status of the kwarg other.
- line{
None
, “45”, “s”, “r”, q”},optional
Options for the reference line to which the data is compared:
“45” - 45-degree line
“s” - standardized line, the expected order statistics are scaled by the standard deviation of the given sample and have the mean added to them
“r” - A regression line is fit
“q” - A line is fit through the quartiles.
None - by default no reference line is added to the plot.
- exceedbool,
optional
If False (default) the raw sample quantiles are plotted against the theoretical quantiles, show the probability that a sample will not exceed a given value. If True, the theoretical quantiles are flipped such that the figure displays the probability that a sample will exceed a given value.
- ax
AxesSubplot
,optional
If given, this subplot is used to plot in instead of a new figure being created.
- **plotkwargs
Additional arguments to be passed to the plot command.
- xlabel{
- Returns
Figure
If ax is None, the created figure. Otherwise the figure to which ax is connected.
