R help - Oct 2015 - Regressing the residuals on the country dummies

I?m trying to estimate a model regressing the residuals on the country dummies
as follows;
model.resC <- lm(model2$res ~ as.factor(Country))
summary(model.resC)

As I call the model I get the following results regarding the residuals:

"ALL 90 residuals are 0: no residual degrees of freedom!"

What has gone wrong?

Hi: You'd have to provide a dput of "model2" and
"Country" for anyone to
give a definitive answer but my guess is that you have an orthogonal X
matrix which is causing you to fit the
model perfectly which causes the model residuals to be zero.

Also, you didn't explain what you're doing but modelling residuals by
using
purely factors doesn't sound like something one would want to do ? I could
be mistaken since
I don't know the context but  you should explain what exactly what your
goal is and your reasoning for doing what you're doing.

Hi,

You have panel data or cross-sectional data? In the case you use cross-sectional
data and "countries" are your observations (no repeated measure of
them) and you regress the country-dummies on your residuals of the forgone
regression, then there are as many regressors as observations. Consequently, is
it not possible to estimate such a model since there are no degrees of freedom
left.

Mit freundlichen Gr??en

Dear All,

I am wondering if someone knows an R equivalent of the following API call
in python.

"-----"

import time
import pandas as pd
start_time = time.clock()
timer =time.clock()
import pkg_resources
pkg_resources.require("pysimplesoap==1.05a")
from pysimplesoap.client import SoapClient


import os
import numpy as np

            client = SoapClient(wsdl="
https://solardata.com/service.asmx?wsdl")
            result = client.GetCsvWeatherData8(
                userName='alex at solardata.com',password='passw at
word1
',licenseNumber='X1952c9wv',
                latitude=lati, longitude=loni,
                startDate='2013-02-10T00:00:00',
endDate='2014-11-28T00:00:00',
                dataVersionId=8,
                spatialResolutionId='High1km',
                timeResolution='Minute',
                missingDataHandling='Blank',
                WindTemp=1,
                timeshift = 'No')

            weather ={}
           
weather['csvWeather']result['GetCsvWeatherData8Result']['csvWeather']

Thanks,

Alemu
