D-optimally Lack-of-Fit-Test-efficient Designs and Related Simple Designs

open access: yesAustrian Journal of Statistics, 2016
In practice it is often more popular to use a uniform than an optimal design for estimating the unknown parameters of a linear regression model. The reason is that the model can be checked by a uniform design but it cannot be checked by an optimal design

D-Optimal Designs for Binary and Weighted Linear Regression Models: One Design Variable

open access: yesMathematics, 2023
D-optimality is a well-known concept in experimental design that seeks to select an optimal set of design points to estimate the unknown parameters of a statistical model with a minimum variance.

MCML D-Latch Using Triple-Tail Cells: Analysis and Design

open access: yesActive and Passive Electronic Components, 2013
A new low-voltage MOS current mode logic (MCML) topology for D-latch is proposed. The new topology employs a triple-tail cell to lower the supply voltage requirement in comparison to traditional MCML D-latch.
