Introduction

The study relates to regression analysis with aims to analyze the statistical data; moreover, the key objective of the study is to forecast the data trend. The objective of regression analysis is to figure out the qualities of parameters for a capacity that make the capacity best fit a set of information perceptions that you give.

Hypothesis

HO 1: There is an association of unit price with stock at beginning of month.

HO 2: There is an association of unit price with deliveries.

HO 3: There is an association of unit price with stock at end of month.

HO 4: There is an association of unit price with this month's sales.

Variables

Dependent variable

The dependent variable for the study is unit price.

Independent variables

The independent variables for the study include is stock at beginning of month, deliveries, stock at end of month and this month's sales.

Statistical Technique

Regression analysis permits you to model, inspect, and investigate spatial relationships, and can assist clarify the elements behind watched spatial examples. Regression analysis is additionally utilized for expectation. You might need to comprehend why individuals are steadily burning out youthful in certain locales, for instance, or might need to foresee precipitation where there are no drizzle checks (Cooper and Weekes, 2005).

Regression is the best known of all regression strategies. It is likewise the best possible beginning stage for all spatial regression investigations. It gives a worldwide model of the variable or handle you are attempting to grasp or expect (early death/rainfall); it makes a solitary regression comparison to stand for that process. GWR that is Geographically Weighted Regression is one of a few spatial regression procedures, in an every expanding degree utilized as a part of topography and different controls. GWR furnishes a neighborhood model of the variable or handle you are attempting to predict and understand by fitting a regression mathematical statement to each characteristic in the dataset. The point when utilized legitimately, the aforementioned routines are influential and solid statistics for estimating and examining direct relationships (Reiss and Thomas, 2007).

Linear relationships are either positive or negative. In the event that you discover that the amount of pursuit and salvage occasions increments when daytime temperatures climb, the relationship is said to be certain; there is a positive relationship. A different route to express this positive relationship is to say that pursuit and salvage occasions diminish as daytime temperatures diminish. Then again, assuming that you discover that the amount of wrongdoings goes down as the amount of cops watching a territory goes up, the relationship is said to be negative (Keith, 2006). You can additionally express this negative relationship by stating that the amount of law violations expands as the amount of watching officers diminishes. Regression analysis could be utilized for a vast assortment of requisitions:

Modeling property misfortune from blaze as a capacity of variables for example level of blaze section association, reaction time, property estimation, and so on. Assuming that you discover that reaction time is the ...
