This applet allows you to read in a TIMESLAB data set that is stored on your computer. It will then display the correlogram and the sample spectral distribution function as well as performing two different tests for white noise.
The supported format is that the data file must be a text file. The first line is the label for the dataset (less than 80 characters), the second line is the number of observations in the dataset. The subsequent lines are the data observations where observations are separated by white space (spaces, tabs, newlines). A sample is given here
Sample time series 10 1.2 2.3 4.5 5.6 3 2 4.5 7.8 9.0 5.2
