hi,

The new version of the periodogram add-in is updated, it now supports kernel density estimation. thanks for your comments and suggestions.

thank's I'm very appreciated

hi, you can add an option like log scale (checked or unchecked) see the picture below.
I would be very happy if you accept my simple suggestion.
best regards.

Hi ecofin,

Do you mean log(frequency- abscissa) or log( (a^2+b^2)^(1/2)- ordinate)? the two options could be calculated using the data from the output table with the @log(x) command. The logarithmic scale can be helpful when the data have a wide range of values, however I think that its utility is minimal in spectral analysis so I do not think necessary to add it as an option.

thanks for the suggestion.

hi
I mean the periodogram and the spectrale density ordinate (y-axis) in output graph and output table data (log scale for ordinate checked or unchecked option), I HAVE SEEN THAT SOME FREE SOFTWARE LIKE Gretl and Jmulti can make this option, it help to apply examples books and for my research.
you can review my suggestion.

Best regards. ecofin
