[R] apply weight to a data frame
I am a beginner user of R. I am writing the master thesis using a data frame from a national survey. The data frame contains several variables, one of which contains the survey weights. I need to apply the survey weights to the data frame, in order to use the data frame with the plm package (I need to run a fixed effect analysis). I know that I could use packages different from plm, but I am more interested in weighting the data frame. Thank you in advance.

[R] Run a fixed effect regression and a logit regression on a national survey that need to be "weighted"
I am a beginner user of R. I am using a national survey to test what variables influence the partecipation in complementary pensions (the partecipation in complementary pension is voluntary in my country). Since the dependent variable is a dummy (1 if the person partecipate and 0 otherwise) I want to run a logit or probit regression; moreover I want to run a fixed effect regression since I subset the survey in order to have only the individuals interviewed more than one time. The data frame is composed by several social and economical variables and it also contain a variable "weight" which is the survey weight (they are weighting coefficients to adjust the results of the sample to the national data). family pers sex income pension1 101 F 1 12 201 F 2 13 202 M 4 04 30 1 M 25000 05 302 F 5 06 401 M 6 1 pers is the component of the family and pension takes 1 if the person partecipate to complementary pension (it is a semplification of the original survey, which contains more variables and observation (aroun 22k observations)). I know how to use the plm and glm functions for a fixed effect or logit regressoin; in this case I don't know what to do since I need to take account of the survey weights. I used the svydesing function to "weight" the data frame: df1 <- svydesign(ids=~1, data=df, weights=~dfweight) I used ids=~1 because there isn't a "cluster" variable in the survey (I know that the towns are ramdomly selected and then individuals are ramdomly selected, but there isn't a variable that indicate the stratification). At this point I am lost: I don't know if it is right to use the survey package and then what function use to run the regression, or there is a way to use the plm or glm functions taking account of the weights. I tried so hard to search a solution on the website but if you could give me an answer I'd be glad.

Re: [R] Run a fixed effect regression and a logit regression on a national survey that need to be "weighted"
Thank you for the answer but I had already tried that way; when I introduce weights in the glm appears the error: Warning: non-integer #successes in a binomial glm! I tried to run the glm regression using the family quasibinomial: eq <- glm(pip ~ men + age_pr + age_c + I(age_pr^2) + I(age_c^2), weights = dfweights, data = df, family = quasibinomial(link = "logit")) Do you think it could be a right solution? 2016-09-20 18:23 GMT+02:00 Adams, Jean : > If you want your records to be weighted by the survey weights during the > analysis, then use the weights= argument of the glm() function. > > Jean > > On Tue, Sep 20, 2016 at 5:04 AM, laura roncaglia < > roncaglia.la...@gmail.com> wrote: > >> I am a beginner user of R.

[R] Manage unbalanced panel with plm
Dear all,
I am using an unbalanced panel dataframe to run my analysis. The df is
based on a national survey and I know the reason why the df is unbalanced.
I tried to understand if plm package corrects for unbalanced panel, so that
I can use the plm package without problem.
I create a plm.data using the following code:
dd.p <- plm.data("id", "year")
and then run fixed effect regression, like this one:
fe1 <- plm(pens ~ woman + age + sqage + high + medium, model="within",
effect="individual", data=dd.p)
So is my approach correct? Does the plm actually correct for unbalanced
panel?
Instead if I need to balance the panel I'd use this code:
dd <- dd %>%
group_by(id) %>%
fileter(n()>2)
(the df is from 2010 to 2013, filtering only id present more than 2 times
would mean that I take only people present three times)
Thanks in advance
