Hi Statalisters,

I faced a problem with the ppplot command by Nicholas J. Cox.

First, I want to edit the graph, but everytime...

• ## Implementing a measure for the goodness of fit for each quantile

Dear Statalisters,

I want to include a measure I saw in a paper called Krüger, S./Rösch, D. (2017): Downturn LGD modeling using quantile...

• Hi Scott,

thank you so much. That helped a lot and is nearly what I intended. 2 follow-ups:

• ## Measures to compare distributions and the Probability-Probability-Plot

Hi Statalisters,

I want to compare the distributional fit of predicted values with the original data. The user written Stata command 'ppplot'...

• ## [FMM] Estimating centiles/graphing density of a single observation

Dear Statalisters,

I want to estimate centiles for a single observation after using a finite mixture model (Mixture of 4 Gaussians/normal...

• ## Computation of densities for exemplary observations with Finite Mixture Model (FMM) and Quantil Regression (QR)

Dear Statalist,

I want to use a Finite Mixture Model (4 Gaussian's) and a Quantile Regression to compare the distributional fit of those...

• ## Finite Mixture Model (FMM) with discrete and continuous part

Dear Statalist,

I have observations in the intervall [0,1] with two modes at 0 and 1. I want to model this data in the following way

• ## Implementing a mixture model of Gaussians in Stata

Dear Statalisters,

for my thesis I need to compare and evaluate statistical models provided by the literature concerning my subject. It is...

• Hi Fernando,
thanks for your help I appreciate it since I'm new to Quantile regressions. I try to express myself a bit clearer. Suppose I want to...

• Hi,

how would the code look like, if I have only one existing variable, but want to generate more than one (e.g. three or four) additional...

• Hi Fernando,
thanks for your suggestion. What I try to aim for is to predict y as accurate as possible by using a quantile regression (not only...
