In this paper, we derive a nonlinear equation of corneal asphericity (Q) using the tangential radius of curvature (rt) on every semi-meridian. We transform the nonlinear equation into the linear equation and then obtain the Q-value of corneal semi-meridian by the linear regression method. We find the 360 semi-meridional variation rule of the Q-value using polynomial function. Furthermore, we co...

Fuzzy linear regression models are used to obtain an appropriate linear relation between a dependent variable and several independent variables in a fuzzy environment. Several methods for evaluating fuzzy coefficients in linear regression models have been proposed. The first attempts at estimating the parameters of a fuzzy regression model used mathematical programming methods. In this the...

The release rate of liquid core material from microcapsules is crucial for the surface properties self-protective metal/liquid microcapsule composite plating coating. However, there no method to accurately predict microcapsules. In this paper, permeability experiments different shell membranes and materials were carried out using weight loss method, model was studied based on a multiple linear ...

This study approaches the least-squares method for simple linear regression model. The line does not comply with data when there are outliers that have deceptive effects on results in dataset. aims to develop a obtaining complies more
