Series quintile_1_ranks should take the value from the series ranks_ret if it is below 0.2 or 0.2 else and so on...

Re: Creating dummies that vary over time and across funds

Hi Gareth Thanks for your help. I was able to create a new series that contains ranks (from 0 to 1) named ranks_ret instead of the return.The next step is to split this series into quintiles which I thought is rather simple. For example, to calculate the quintile 1-3 I did: Quintile_1_ranks=@min(0.2...

Re: Creating dummies that vary over time and across funds

Isn't there a way to normalize a return series (stacked data) to a series that takes values between 0 and 1? In Excel, I would calculate the following for each a cross section: To get rid of the negative values: abs_series = return_series+abs(min(return_series)) To get values between 0 and 1: rank_s...

Re: Wrong datatype in CSV import

Hi Gareth

Can I send it by e-mail?

The CSV file is organized as a stacked panel file (monhtly data) and I have about 6 variables in the file which should all have numeric datatypes. But somehow, Eviews incorrectly recognizes two o...

Re: Creating dummies that vary over time and across funds

Hi Gareth The dummy creation worked fine but now I'd need your help on the following: For the same panel, I need to assign percentile ranks to the variable ln_return. In particular, I'd like to create a new series that instead of the ln_return states the percentile rank for the fund compared to its ...

Re: Creating dummies that vary over time and across funds

Hi Gareth Many thanks for your reply. I started with the function in 1. and a pop-up window said that "median" is not defined. What is the exact function I need to use to calculate the median as described in 1. ? Isn't there a function to calculate this similar as calculating a log by just...
