将OLS回归摘要打印到文本文件 [英] Print OLS regression summary to text file
本文介绍了将OLS回归摘要打印到文本文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在使用 groupby
和以下代码使用 pandas.stats.api.ols
运行OLS回归:
I am running OLS regression using pandas.stats.api.ols
using a groupby
with the following code:
from pandas.stats.api import ols
df=pd.read_csv(r'F:\file.csv')
result=df.groupby(['FID']).apply(lambda d: ols(y=d.loc[:, 'MEAN'], x=d.loc[:, ['Accum_Prcp', 'Accum_HDD']]))
for i in result:
x=pd.DataFrame({'FID':i.index, 'delete':i.values})
frame = pd.concat([x,DataFrame(x['delete'].tolist())], axis=1, join='outer')
del frame['delete']
print frame
但这会返回错误:
AttributeError: 'OLS' object has no attribute 'index'
我的小组中大约有2,000件物品,当我打印出每件物品时,它们看起来像这样:
I have about 2,000 items in my group by and when I print each one out they look something like this:
-
------------------------Summary of Regression Analysis-------------------------
Formula: Y ~ <Accum_Prcp> + <Accum_HDD> + <intercept>
Number of Observations: 79
Number of Degrees of Freedom: 3
R-squared: 0.1242
Adj R-squared: 0.1012
Rmse: 0.1929
F-stat (2, 76): 5.3890, p-value: 0.0065
Degrees of Freedom: model 2, resid 76
-----------------------Summary of Estimated Coefficients------------------------
Variable Coef Std Err t-stat p-value CI 2.5% CI 97.5%
--------------------------------------------------------------------------------
Accum_Prcp 0.0009 0.0003 3.28 0.0016 0.0004 0.0015
Accum_HDD 0.0000 0.0000 1.98 0.0516 0.0000 0.0000
intercept 0.4750 0.0811 5.86 0.0000 0.3161 0.6340
---------------------------------End of Summary---------------------------------
我希望能够将每个导出到csv,以便可以分别查看它们.
I want to be able to export each one to a csv so that I can view them individually.
推荐答案
为了写出 pandas.stats.api.ols
的结果
,请使用文本文件以匹配输出格式,例如:
In order to write out the result
of pandas.stats.api.ols
, use a text file to match the output format, for instance:
from pandas.stats.api import ols
grps = df.groupby(['FID'])
for fid, grp in grps:
result = ols(y=grp.loc[:, 'MEAN'], x=grp.loc[:, ['Accum_Prcp', 'Accum_HDD']])
text_file = open("Output {}.txt".format(fid), "w")
text_file.write(result.summary)
text_file.close()
