This function requires that the input data frame contains a column named 'walk_number' and that the value to summarize is provided. It computes statistics such as mean, median, variance, and quantiles for the specified value variable. #' This function summarizes a data frame containing random walk data by computing various statistical measures for a specified value variable, grouped by a specified grouping variable. It checks for necessary attributes and ensures that the data frame is structured correctly.
