Sklearn time

WebbIntroduction¶. A time series is a succession of chronologically ordered data spaced at equal or unequal intervals. The forecasting process consists of predicting the future value of a time series, either by modeling the series solely based on its past behavior (autoregressive) or by using other external variables. Webb11 juli 2024 · This repo demonstrates the model of Linear Regression (Single and Multiple) by developing them from scratch. In this Notebook, the development is done by creating all the functions, including Linear Regression for Single and Multiple variables, cost function, gradient descent and R Squared from scratch without using Sklearn.
