Hello all; Ihave three questions. The first one was posted two often in this forum but still no response. Second, I need a precision about the equation used to test the stability of my model. Do I estimate equation with original series (which is spurious REGRESSION) or with stationnery séries. Thire...

hi evryone my question may be idiot but i can not take decision about my serie if it is differency stationary (and it is then I(2) without constant) or trend stationary and then I(1) here are the results of ADF and PP tests. I made a df test on the trend wicth critical value à is 2.78 (5%) ADF t-@re...

It works for me to and i find 0.855305.
Thanks a lot.

here in attachement i give you one exemple of série denominated yy. i want to calculate the probability of yy is in the interval [-0.025; +0.025].
in eviews i set @mean (yy>-0.025 and yy<0.025) and gives me a message i sent before.
thanks

Hello;
thank you for ansewer, but it doesen't work. The message given by eviews is: "scalar sent to function which operates on a matrix"

hi;
i have series of observations and want to calculate the probability of a given interval, for example: [-0.025; +0.025]. thanks
