+    parse_log(log)
+
+Parse a log of actions and extract model fitting entries into a dictionary.
+
+# Arguments
+- `log`: A list of tuples representing log entries.
+
+# Returns
+A dictionary where keys are model names and values are lists of dictionaries,
+each containing model parameters, error, and index from the log.
+
+# Example
+```julia
+data.log = [...]  # Define your log data
+models_data = parse_log(data.log)
+println(models_data)
