This package is used for time series data analysis. Added a variety of drawing functions, evaluation indicators, and simple moving average. Delete the moving average model.
Project description
TimesML
About
This package was developed for time series data analysis and machine learning tasks. The aim of TimesML is to provide high-level APIs that developers and data scientists can easily model their times series data. We plan to support more machine learning models in the future. Thank you for your support, please star⭐ this project if you like.
List of module

Simple example
import TimeSeriesAnalysis.ProcessData as Data
import TimeSeriesAnalysis.Model as Model
import TimeSeriesAnalysis.Chart as Chart
# setting parameters
save_path = 'US'
chart = Chart.chart('US')
# read data
data = Data.read_file(path='test_data/g20_new_c.csv', col_name='US')
# contains basic statistics: historocal trend line chart、lag plot、ACF chart. figure 1.
chart.statistics_infographic(data, file_path=save_path, lags=20, xlabel='date', ylabel='population')
# split data into training set and test set
train, test = Data.split_data(data, ratio=0.7)
# autoRegressive
model = Model.AutoRegressive(lags=2)
model.fit(train)
model.predict(test, pure_test_set_predict=True)
model1 = Model.AutoRegressive(lags=20)
model1.fit(train)
model1.predict(test,pure_test_set_predict= True)
# Save data
Data.save_flie(model1.test_predict, path=save_path, stock_id='US', file_format='csv')
# Combine and compare the prediction results of the two models. figure 2.
chart.forecast_result_group_chart(train, test, model, model1, file_path=save_path,
model_1_name='AR(2)', model_2_name='AR(20)', xlabel='date', ylabel='population')
# simple moving average
model2 = Model.SimpleMovingAverage(windows=5)
model2.fit(data)
# line chart to observe the average situation every five days. figure 3.
chart.line_chart(data, model2.sma_result, chart_title='SMA(5)', file_path=save_path, xlabel='date', ylabel='price')
