This function generate temperature predictions (in 10^6/T2) based on a calibration dataset and target D47. Note that this approach additionally accounts for measured error in the target D47. This approach is congruent with the one used in McClelland et al. (2022).
This function generates temperature predictions (in 10^6/T2) based on a calibration dataset and target D47. It includes measured error in the target D47 and ion as an additional predictor.
