R Documentation

Estimate missing records for standard deviation based on mean of body size

Description

Fill in missing records for the standard deviation of body mass for a species, based on its mean body size and the parameters estimated by the linear model fit by get_sd_parameters.

Usage

add_estimated_sds(clean_size_data, sd_pars)

Arguments

`clean_size_data`	dataframe of species' masses and standard deviations; as generated by `clean_sp_size_data`
`sd_pars`	parameters as list of `⁠$slope⁠`, `⁠$intercept⁠`; as generated by `get_sd_parameters`

Value

a dataframe of species' species_id (which matches the AOU in the Breeding Bird Survey), mass mean body mass, sd standard deviation body mass, and a new column for estimated_sd, a TRUE/FALSE flag for whether the standard deviation has been estimated using the parameters provided in sd_pars.
