Re: [R] Unable to Understand Results of pglm function

2019-04-23 Thread Paul Bernal
Hi Dr. Mackay, Thank you so much for your valuable feedback. I wonder why, when applying the summary function over the pglm model, it shows infinite as value for the standard errors. Is this something we should expect? Or is there something else that needs to be adjusted, either in the dataset(

Hi Paul I think you may have too many IDs DATE for your model as you posted I converted your DATE into date format and named it df3 str(df3) 'data.frame': 527 obs. of 11 variables: $ TRANSIT : int 1 1 1 0 1 1 1 1 1 1 ... $ ID : int 1 1 2 2 3 4 5 5 6 7 ... $ DATE: Fact

Dear Yves, Hope you are doing great. I have been testing the pglm function from the pglm package, in order to fit a logit regression to a panel dataset, and I do not understand the results and/or errors produced by the function, so I want to be able to understand whether there is a problem with th

[R] Vectorised uniroot function

2019-04-23 Thread Mark Clements
A vectorised uniroot function would be useful for function inversion, e.g. for quantile functions and random number generation. To address this, I have implemented rstpm2::vuniroot that adapts the C function R_zeroin2 for Brent's method for a vectorised objective. The function currently uses Rcpp,

2019-04-23 Thread Gabor Grothendieck
lag.zoo supports vector-based lags on zoo objects. A few caveats: - dplyr's lag clobbers the base R lag (which you need to invoke lag's methods) so if you have dplyr loaded be sure to refer to stats::lag. - dplyr's lag works backwards relative to the standard set in base R so dplyr::lag(x, 1) cor
