Summarize Walks Data
Description
Summarizes random walk data by computing statistical measures.
Usage
summarize_walks(.data, .value, .group_var)
summarise_walks(.data, .value, .group_var)
Arguments
.data |
A data frame or tibble containing random walk data. |
.value |
A column name (unquoted) representing the value to summarize. |
.group_var |
A column name (unquoted) representing the grouping variable. |
Details
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.
Value
A tibble containing the summarized statistics for each group, including mean, median, range, quantiles, variance, standard deviation, and more.
