Most of the time, 95 percent is the standard value for the confidence interval. This means that Excel is 95 percent confident that the predicted value will fall between those two lines. Seasonality defines the repeating nature of your timeline.Feb 19, 2018
1. Introduction
Time-series forecasting models are the models that are capable to predict future values based on previously observed values. Time-series forecasting is widely used for non-stationary data. Non-stationary data are called the data whose statistical properties e.g.

Introduction
Even though there are myriad complex methods and systems aimed at trying to forecast future stock prices, the simple method of linear regression does help to understand the past trend and is used by professionals as well as beginners to try and extrapolate the existing or past trend into the future.
Understanding linear regression
The simplest form of the regression equation with one dependent and one independent variable is defined by the formula
Analyzing the past trend
Taking the past prices of INFY from 09-Apr-2020 till 10-Jul-2020, a total of 60 trading days or roughly 3 calendar months and by following the below procedure, we will get the past 60-day trend of Infosys.
Limitations
The future is shown as a linear increase which is not true as if you observe the actual values you see a jump up and a fall down in the prices. There is a lot of variability in the actual data but a standard increase in the forecasted values.
Conclusion
We knew from the past data the rate of the linear increase, we knew that we do not know whether the future is going to be better than the past or worse than the past or equal to the past.

Understanding Linear Regression
- The simplest form of the regression equation with one dependent and one independent variable is defined by the formula y = m*x + c where y is the estimated dependent variable, m is the regression coefficient, or what is commonly called the slope, x is the independent variable and c is a constant. In simple words, y is the output when m, x, and c are used as inputs. Linear regressio…

Usefulness

- Using the percent error, a range could be deduced and it can be expected the future value could lie within this range.
- Once can work out all the cases and become aware of the future values if the trend improves, worsens, or remains the same and so have an idea of the possible ranges.
- It is a quicker and easier method to apply using the most popular analysis tool which is excel and unlike highly complex processes that try harder at forecasting accurate values is much easier to i...
Conclusion
- We knew from the past data the rate of the linear increase, we knew that we do not know whether the future is going to be better than the past or worse than the past or equal to the past. We simply assumed that it will be equal to the past which is the standard assumption one makes when using the simple linear regression model. However, the actual future data in our example p…
