The 'Weight selection' dialog


In the weight selection dialog the user selects the weights which should be used for Fourier and least-squares calculations. Multiple selections are possible. See "Using weights" for a detailed description of setting weights.

Period04 supports 3 types of weights:
weights assigned to substrings of an attribute If you decided to give your substrings different weights in one or several of the four attributes and you want to include them in the calculations, then select the appropriate attribute weight.
point weight If you read in a point weight for each of your data points and want to use them in your calculations, then select this weight.
deviation weight If this option is active the data points will be weighted based on their residual value. Cutoff defines a limit residual value. If the residual of the data point is within this limit, then its weight is set 1.0, otherwise the weight will be calculated based on the residual and the cutoff value.

See "Using weights" for more information on using weights.
