### Confidence ellipse / eigenvectors

I want to create a 95% confidence ellipse over my x y scatter plot. Here is a reference visual: error_ellipse1.png I have not found anything in the eviews GUI, but perhaps there are some features I can use to help me. If eviews doesn't have built-in support for confidence ellipses, where can I find ...

### survival analysis

If I'm not mistaken there is not a dedicated survival analysis model in eviews. but there is poisson regression functionality. So I think survival analysis could still be feasible in eviews, however I'd like to find a minimal worked out example of such a procedure because all the existing literature...

### An efficient loop for storing sensitivity/specificity

I want to create a matrix that stores the sensitivity and specificity of my probit model at all thresholds from .01 to 1.00. So I create a 100x3 matrix and wrote this loop: %dep = "my_binary_var" %eq = "my_equation" matrix(100,3) my_matrix for !i = 1 to 100 !threshold = !i/100 fr...

### Re: Optimization Method for Least Squares

You are more knowledgeable about this than myself, but from what I understand, technically OLS is still a matter of convergence, it just tends to converge after only 1 iteration. Let me try to rephrase my question. OLS is a simple method, it doesn't need a fancy convergence method per say. However, ...

### Optimization Method for Least Squares

I noticed with some methods the convergence method is shown at the estimation output screen, but with OLS the convergence method is omitted. I checked the documentation, but couldn't find details about the convergence method of OLS. Getting OLS to converge is hardly a challenge, but I'm guessing und...

### Single Graph Plotting of Group

Hello! I have a group called xs, and I am trying to create a program that will plot each series of the group's kernel densities. I have gotten that far at least, however I am not sure how to combine them into one graph. Here is my code: group xs price_b price_c price_d price_g xs.distplot kernel Whe...
