# quantile-regression

##### 有没有一种简洁的方法可以用 geom_quantile() 中的方程和其他统计数据来标记 ggplot 图？(Is there a neat approach to label a ggplot plot with the equation and other statistics from geom_quantile()?)

##### Is there a neat approach to label a ggplot plot with the equation and other statistics from geom_quantile()?

I'd like to include the relevant statistics from a geom_quantile() fitted line in a similar way to how I would for a geom_smooth(method="lm") fitted linear regression (where I've previously used ggpmisc which is awesome). For example, this code: # quantile regression example with ggpmisc equation # basic quantile code from here: # https://ggplot2.tidyverse.org/reference/geom_quantile.html library(tidyverse) library(ggpmisc) # see ggpmisc vignette for stat_poly_eq() code below: # https://cran.r-project.org/web/packages/ggpmisc/vignettes/user-guide.html#stat_poly_eq my_formula <- y ~ x #my

##### R - Setting margins does not work

I estimated a linear regression model by using the quantreg package. I now want to display the results graphically by using the plot() function: plottest = plot(summary(QReg_final), parm=2, main="y",ylab="jjjjj") The result is the following (I can only link the image yet): Example As you can see at the very left, the description of the y-axis is cut off. I then tried to adjust the margin parameters, but it seems to have zero influence on the plot. For example: par(mar=c(10,10,2,2)) When I now run the above mentioned code, it results in the exact same plot. On the other hand, when plotting

##### python statsmodels: Difference in output “formula.api” vs. “”regression.quantile_regression"

For the modul statsmodels using python, I would please like to know how differences in calling the same procedures using statsmodels.formula.api versus statsmodels.regression.quantile_regression come about. In particular, I obtain differences in parameter estimates. A minimum working example is attached. #%% Moduls; import numpy as np import pandas as pd import statsmodels.api as sm import statsmodels.formula.api as smf from statsmodels.regression.quantile_regression import QuantReg #%% Load in sample data; data = sm.datasets.engel.load_pandas().data #%% smf-Version; model1 = smf.quantreg
