I'm trying to replicate this paper but using different time period
https://www.dropbox.com/s/edwdpgwsbli93f1/SM35%282%29-09-modelling.pdf?dl=0.
This paper is about detecting regime shifts in Malaysian currency i.e the ringgit. From what I understand it uses Markov Switching-Autoregressive method (MS-AR). I've been trying to replicate this method in R, but to no success. There has been some question asking about it lately which can be found here
Error when using msmFit in R
Basically I'm having the same problem. When I tried to do the MS-AR the error came out. I'm not sure what the exact calculation for the msmFit, but from some examples online they use this to get the fit for MS-AR. So my question is, is it actually possible to do MS-AR(p) in R? Is there any other software besides R or Eviews 8 (since I don't have this at the moment) that can actually do this?
Thank you. Really appreciate your insight.

There is a package for MATLAB called MS_Regress, it should do the job:

I was trying to fit the MS-AR model in R, but I get the same error message. Could you provide us with a link to the examples you found about getting the fit in R?

I am looking at this code, previously v-transformations were done and fitting VT-ARMA copula models, now here it is applying shapiro test to residuals and want to plot 4 graphs:
https://i.stack.imgur.com/gTtBU.png
These 4 plots should come out of plot(vtcop, plotoption=3) etc... I have never used this argument plotoption, i think this argument is contained in the tscopula package ,but I have already done the necessary research on the help and read the pdf file that explains the tscopula package but there is no such "plotoption".
Can anyone tell me why it tells me unused argument at this point?
This code from by paper of AlexanderMcNeil: "Modelling Volatile Time Series with V-Transforms and Copulas".
Thank you very much. Good day.
I used Caret to create a regression model of a dataset in R, and I wish to find this equation for usage in other websites (e.g. Desmos). I am unable to find info anywhere on how to do this, so if anyone has answers, that would be much appreciated! :D
Currently I'm interested in learning how to obtain information from the American Community Survey PUMS files. I have read some of the the ACS documentation and found that to replicate weights I must use the following formula:
And thanks to google I also found that there's the SURVEY package and the svrepdesign function to help me get this done
https://www.rdocumentation.org/packages/survey/versions/3.33-2/topics/svrepdesign
Now, even though I'm getting into R and learning statistics and have a SQL background, there are two BIG problems:
1 - I have no idea what that formula means and I would really like to understand it before going any further
2 - I don't understand how the SVREPDESIGN function works nor how to use it.
I'm not looking for someone to solve my life/problems, but I would really appreciate if someone points me in the right direction and gives a jump start.
Thank you for your time.
When you are using svyrepdesign, you are specifying that it is a design with replicated weights, and it uses the formula you provided to calculate the standard errors.
The American Community Survey has 80 replicate weights, so it first calculates the statistic you are interested in with the full sample weights (X), then it calculates the same statistic with all 80 replicate weights (X_r).

I'm working on spatio-temporal anomaly analysis using R.
I found a lot tutorials talking about converting data into STFDF( space-time full data frame) and use variogram method and then use stkrige function for prediction. And so I did. However, I found some research papers talking about STARIMA model , which is basically, ARIMA model but for space time data.
Couldn't find any example how to implement it using R.
Does anyone have an idea how to implement it?
Also, how does STARIMA is related to variogram?
The reason why I'm asking is because when I used variogram and pull the plot for the time series of my data, I see outliers, and I couldn't find tutorials explains how to detect outliers with variogram. Anyone went through this topic before?
Thanks
I need help for my problems. I have 2 problems.
I can't install library (VGAM) on my RStudio. Have any idea for another regression logistic ordinal package or have solution for my problem?
I Stuck for the first step when used mlogit. I have dependent variable = Kategori.Kredit with 3 option. And I have independent variable = FD,FC,ND,NC,CASA. Please help me to solve this problem, I try read example on pdf but still didn't understand.
Please, don't post two completely different questions at the same time.

About number 2, it seems that your data is in the wide format, while mlogit need it in the long one. Use the function mlogit.data to get your data ready. The manual has some good examples about mlogit.data
