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

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)
