I am running a logistic regression and reporting the results with stargazer. I've noticed that when I apply the apply.coef = OR option (so that the odds ratios would be reported), the significance stars are reported wrongly - in some cases there is no stars instead of three, sometimes there are stars when there shouldn't be. For example;
stargazer(basic.logit.model,
type="html",
apply.coef = OR,
column.labels = c("Base"),
dep.var.labels.include = FALSE,
digits=2, out=("basic_model_only.htm"))
yields
X 0.33
(0.23)
Constant 0.03
(0.11)
Observations 6,532
Log Likelihood -552.64
Akaike Inf. Crit. 1,109.28
Note: *p<0.1; **p<0.05; ***p<0.01
and without the apply-coef option, the results are:
X -1.10***
(0.23)
Constant -3.68***
(0.11)
Observations 6,532
Log Likelihood -552.64
Akaike Inf. Crit. 1,109.28
Note: *p<0.1; **p<0.05; ***p<0.01
what am I missing?
generally you should strive to provide a minimal working example so we can reproduce your results - in this case it would be great to have data and the code you use to produce your basic.logit.model
.
To your question, apply.coef
only transforms your coefficients but not the standard errors as your results show. stargazer calculates the significance level using these untransformed SEs which results in non-significant coefficients.
To avoid this, provide stargazer with the custom p-values (those from the original model) using the p
argument.
This should work for you
p.values <- list(summary(basic.logit.model)$coefficients[,4]
stargazer(basic.logit.model,
type="html",
apply.coef = OR,
p = p.values,
column.labels = c("Base"),
dep.var.labels.include = FALSE,
digits=2, out=("basic_model_only.htm"))
