The factor and regression characterization of the broad-band variable attenuator with large dynamic range and low insertion phase shift
P. 1–4.
Mirmanov A., Stukach O.
Statistical modeling methods, in particular, the factor and multiple regression analysis are offered to use for the variable attenuator design. It is shown that the statistical methods which are earlier not used for decision of the given problem, allow to reveal physical laws of elements operation in device. It promotes creation of structure with minimum phase shift at regulation of transfer factor or insertion loss. At the controlled attenuator design it is necessary to reveal the factor loadings separately influencing to phase variation and insertion loss. Revealing and interpretation of the factor loadings influencing to investigated characteristics, allows to change the traditional methodology and essential simplify optimization of the phase compensating and adjusting parameters of attenuator. The software system Statistica is used for modeling.

If missingness is encountered in a categorical regressor, which approach is preferable: complete case analysis or the missing-indicator method? The former approach implies including in analysis (linear regression in our research) only the cases without missingness across analyzed variables. This approach is embedded in many statistical applications by default, and despite the opinion that its ...
