Machine learning pipelines, similar to data science workflows, start with data collection and preprocessing. The model then takes in an initial set of training data, identifies patterns and relationships in that data, and uses that information to tune internal variables called parameters. The mode...
While Excel (ahem) excels at things like arithmetic and tabulations (and some complex things too, like presentation), R's programmatic focus introduces concepts like data structures, iteration, and functions. Once you've made the investment in learning R, these abstractions make reducing complex ...
Each row in the dataframe consists of a pair of measurements. The Bland-Altman plot has the average of the two measures in a pair on the x-axis. The y-axis contains the difference between the two measures in each pair. Add the averages and differences data to the dataframe. sample_df$...
