خود همبستگی(Auto correlation) سری زمانی در داده هاي سري زماني، مشکل شايع خود همبستگي يا همبستگي پياپي است كه بر روي جملات اخلال در دوره هاي مختلف وجود دارد. يکي از دلايل وجود همبستگي پياپي يا خود همبستگي اين است كه عوامل موثر از سري زماني حذف شده است، عواملي كه مانند متغيرهاي موجود در مدل مهم و با يکديگر ارتباط دارند. import matplotlib.pyplot as plot import numpy as np # Time series data data = np.array([24.40,10.25,20.05,22.00,16.90,7.80,15.00,22.80,34.90,13.30]) plot.acorr(data, maxlags=9) plot.title('Autocorrelation of XYZ stock price data') plot.xlabel('Lag') plot.ylabel('Autocorrelation') plot.show() #پایتون_مالی #همبستگی_سری_زمانی #سری_زمانی

Importantly, that investor viewpoint is not new. It cycles in when conditions are right (and vice versa). It also brings the ineffective warnings of an overpriced market with it.Looking toward a good 2022 stock market, there is no apparent reason to expect these issues to change.
Export WhatsApp stickers to Telegram on iPhone
You can’t. What you can do, though, is use WhatsApp’s and Telegram’s web platforms to transfer stickers. It’s easy, but might take a while.Open WhatsApp in your browser, find a sticker you like in a chat, and right-click on it to save it as an image. The file won’t be a picture, though—it’s a webpage and will have a .webp extension. Don’t be scared, this is the way. Repeat this step to save as many stickers as you want.Then, open Telegram in your browser and go into your Saved messages chat. Just as you’d share a file with a friend, click the Share file button on the bottom left of the chat window (it looks like a dog-eared paper), and select the .webp files you downloaded. Click Open and you’ll see your stickers in your Saved messages chat. This is now your sticker depository. To use them, forward them as you would a message from one chat to the other: by clicking or long-pressing on the sticker, and then choosing Forward.
