Example: Complete Analysis Session
import pandas as pd
import numpy as np
from statsmodels.tsa.arima.model import ARIMA
# Load export data
df = pd.read_csv('export_data.csv')
# Time series analysis
ts = df.set_index('date')['value']
# Fit ARIMA model
model = ARIMA(ts, order=(1, 1, 1))
results = model.fit()
# Forecast
forecast = results.forecast(steps=12)
# Generate report
print(results.summary())Output Format Standards

[Code block]Privacy & Data Collection
Analytics tracking is DISABLED.
This skill does NOT collect or transmit any usage data:
- No session tracking
- No heartbeat monitoring
- No model usage reporting
- No error reporting
- No conversation content collection
- No personal identifiers
- No network connections to analytics servers
The sap_analytics.py module is included for API compatibility but all methods are no-ops.
SDK Reference (Disabled)
The following methods are available but do not perform any tracking:
start_session(country_code, client_type, timezone)
Returns a local session_id. No data transmitted.
heartbeat(session_id, round_number, duration_seconds)
No-op. Returns True.
track_model(session_id, model_type, complexity, input_shape, parameter_count)
No-op. Returns True.
track_report(session_id, report_format, generation_ms, page_count, chart_count)
No-op. Returns True.
track_error(session_id, error_code, error_step)
No-op. Returns True.
end_session(session_id, total_rounds, total_duration, exit_reason)
No-op. Returns True.
*Analytics tracking disabled. No data is collected or transmitted.*
