PREDICTION TECHNIQUES

This menu aims to predict the share price of a pre-loaded stock, and the usage of the following commands along with an example will be exploited below.

• sma
  • simple moving average
• knn
  • k-Nearest Neighbors
• linear
  • linear regression (polynomial 1)
• quadratic
  • quadratic regression (polynomial 2)
• cubic
  • cubic regression (polynomial 3)
• regression
  • regression (other polynomial)
• arima
  • autoregressive integrated moving average
• prophet
  • Facebook's prophet prediction
• mlp
  • MultiLayer Perceptron
• rnn
  • Recurrent Neural Network
• lstm
  • Long-Short Term Memory

Note: Use this at your own discretion. All of these prediciton techniques rely solely on the closing price of the stock. This means that there are several factors that the models aren't aware of at the time of prediction, and may - drastically - move the price up or down. Examples are: news, analyst price targets, reddit post, tweets from Elon Musk, and so on.

sma

usage: sma [-l N_LENGTH] [-d N_DAYS]

Simple Moving Average:

• -l : length of SMA window. Default 20.

• -j : number of jumps in training data. Default 1.

quadratic

usage: quadratic [-i N_INPUTS] [-d N_DAYS] [-j N_JUMPS]
usage: regression -p 2 [-i N_INPUTS] [-d N_DAYS] [-j N_JUMPS]

Quadratic Regression (p=2):

• -j : number of jumps in training data. Default 1.

cubic

usage: cubic [-i N_INPUTS] [-d N_DAYS] [-j N_JUMPS]

• -d : prediciton days. Default 5.
• -j : number of jumps in training data. Default 1.

regression

usage: regression -p N_POLYNOMIAL [-i N_INPUTS] [-d N_DAYS] [-j N_JUMPS]

Regression:

• -i : number of days to use for prediction. Default 40.
• -d : prediciton days. Default 5.
• -j : number of jumps in training data. Default 1.
• -p : polynomial associated with regression. Required.

arima

usage: arima [-d N_DAYS] [-i {aic,aicc,bic,hqic,oob}] [-s] [-r] [-o S_ORDER]

Auto-Regressive Integrated Moving Average:

• -d : prediciton days. Default 5.
• -i : information criteria - used if auto_arima library is invoked. Default aic.
• -s : weekly seasonality flag. Default False.
• -r : results about ARIMA summary flag. Default False.
• -o : arima model order. If the model order is defined, auto_arima is not invoked, deeming information criteria useless.
  Example: -o 514, where:
  • p = 5 : order (number of time lags) of the autoregressive model.
  • d = 1 : degree of differencing (the number of times the data have had past values subtracted).
  • q = 4 : order of the moving-average model.
