remove_cardinal_biases_discrete {circhelp}

Remove cardinal biases for data with orientation (color, motion, ...) set in discrete steps

Description

Remove cardinal biases for data with orientation (color, motion, ...) set in discrete steps

Usage

remove_cardinal_biases_discrete(err, x, space, init_outliers = NULL)

Arguments

err

a vector of errors, deviations of response from the true stimuli

x

a vector of true stimuli in degrees (see space)

space

circular space to use (a string: 180 or 360)

init_outliers

a vector determining which errors are initially assumed to be outliers (default: NULL)

Value

returns a data.table with the following columns:

• is_outlier - 0 for outliers (defined as ±3*predicted SD, where SD and mean are computed after excluding initially assumed outliers)

• be_c error corrected for biases (⁠be_c = observed error - pred⁠)
