quad2Dfit: two-dimensional quadratic fitting for visual-field results

Description

fits a 2D quadratic function using values in val as "observations" for the x and y coordinates in patternMap

Usage

quad2Dfit( val, patternMap = saplocmap$p24d2,
           bspos = vfsettings$p24d2$bs )

Arguments

val

values at each location

patternMap

pattern of stimulus locations. It uses the x and y coordinates in conjunction with val to get the fitted values with the 2D model

bspos

position of the blind spot

Value

• fitted values by a 2D quadratic function
