Heteroskedastic logit Model in R

General
1

Hi everyone,

I am a beginner of R and just joined this group. I am trying to run Heteroskedastic logit in R. I followed the instruction on this link: https://cran.r-project.org/web/packages/mlogit/vignettes/c4.relaxiid.html
Here is a picture of my data

I run the code
library(mlogit)
hl.fdi <- mlogit(province_chosen ~ Z1 + Z2 + Z3 + Z4 + Z5 + Z6|X1 + X2 + X3 + X4,sample1,reflevel = 'Hanoi_city', heterosc = TRUE)
coef(summary(hl.fdi) (as I want to know the scale parameter; sample1 is the name of my dataset which I imported from csv)

However, I got the error
Error in dfidx::dfidx(data = data, dfa$idx, drop.index = dfa$drop.index, :
the two indexes don't define unique observations

Do I need to indicate reference level here? Can you help me with the codes? Is there a way for us to extract part of my data sample and upload here? I am very new to R. I really appreciate any help. Thanks so much!

Can't help with specifics without a reprex. See the FAQ.

Run the example given in the vignette you linked. Before running mlogit(), data must first be transformed with dfidx().

From help(mlogit)

The data argument may be an ordinary data.frame . In this case, some supplementary arguments should be provided and are passed to mlogit.data() . Note that it is not necessary to indicate the choice argument as it is deduced from the formula.

mlogit.data() is not deprecated and dfidx:: dfidx() is now required to prepare the required idnames arguments. For a data frame object, those must be prepared manually.

Thank so much @technocrat for your reply ! I really want to show you my dataset but I am struggling with datapasta and reprex although I have read and followed the instruction.
I followed scenario 1 in this website: Using datapasta with reprex • reprex (tidyverse.org)
but do not know how to paste my data from clip board to this group (as the video does not show).

Created on 2023-04-02 with reprex v2.0.2

and here is my code (
X1...X4: individual specific vars
Z1...Z7: alternative specific vars) but the error is still the same: Error in dfidx::dfidx(data = data, dfa$idx, drop.index = dfa$drop.index, :
the two indexes don't define unique observations
I read about "- dfidx" but still confused how to use in this situation.

library(mlogit)
hl.fdi <- mlogit(province_chosen ~ Z1 + Z2 + Z3 + Z4 + Z5 + Z6|X1 + X2 + X3 + X4,sample3,reflevel = 'Hanoi_city', heterosc = TRUE)```

You can also use the dput(YOURDATA) function and then cut and paste the output from the console pane. If there’s a lot, just need to include enough rows so your code works the same. Like this

dput(head(YOURDATA,100)) # for the first hundred rows only.

Hi @technocrat for replying to me. I posted my data in another post but I was notified by the system that it went into spam, so I wrote another one.

Here is my code and the error is still the same as my first post:
library(mlogit)
hl <- mlogit(province_chosen ~ Z1 + Z2 + Z3 + Z4 + Z5 + Z6|X1 + X2 + X3 + X4,sample3,reflevel = 'Hanoi_city', heterosc = TRUE)

  1. I also want to get scale parameter of the Heteroskedastic logit by a code similar to the code provided in this link https://cran.r-project.org/web/packages/mlogit/vignettes/c4.relaxiid.html: Here is the code they provided and I want a similar code for my data, but I do not know how to create.

I really look forward to your help. Thank you so much!

I've been approaching this as a functional analysis problem in finding the right arguments needed to resolve the error messages and have understood a couple of the underlying issues—the province_name variable needs two be a factor and there must be two columns identified as index columns in the dfidx() function. However, I was still having difficulty resolving an error involving the "reference level."

Going back to read more of the documentation, I saw that this is a model developed in the econometrics field and is designed for specific types of data sets

Data sets used for multinomial logit estimation concern some individuals ... that make one or a sequential choice of one alternative among a set of mutually exclusive alternatives. The determinants of these choices are covariates that can depend on the alternative and the choice situation, only on the alternative or only on the choice situation.

In the data for this question, the choices are a list of localities as 35 mutually exclusive alternatives to be selected by a list of 4 individuals, and 9 numeric variables that are assumed to be relevant to the choice.

However, all individuals made the same choice, effectively focusing attention on a much smaller data object

Noticing the the Z variables were a constant among all individuals, we are left with only the X variables to look to for insight.

And among the X variables, two individuals report identical values. The remaining eight data points don't leave much to go on.

This means I need better to understand if this is the extent of the data and, if it is, what question the mlogit approach is meant to illuminate?

Hi. Thank you for being considerate. Z1.....Z6 are alternative specific variable and X1...X4 are individual specific. I am most interested in examining the effect of X1...X4 on the probability of choosing alternatives. Really appreciate your help. It seems I need a lot to learn about R and this methodology.

@nhungntk1005, let me ask a follow-up question from my reading of @technocrat's reply. @technocrat writes "all individuals made the same choice." If the dependent variable is identical for all observations, then there is no way to use multinomial logit--or any other statistical method--to find out what influenced the choice. Hopefully, I am misunderstanding the data.
