Regression analysis is based on the assumption that the dependent variable is distributed according some function of the independent variables together with independent identically distributed random errors. If the error terms were not stochastic then some of the properties of the regression analysis are not valid.
The stochastic error term in regression analysis represents the variability in the dependent variable that is not explained by the independent variables. It captures the random fluctuations or unobserved factors that affect the dependent variable but are not included in the model. The error term is assumed to be normally distributed with a mean of zero and constant variance in classical linear regression models. Understanding and modeling the stochastic error term is crucial for assessing the reliability and accuracy of the regression results.

What is statistics about?
Mathematica can be divided into two parts ; viz. Mechanics, and Statistics. Mechanics deals with the movement of a single object in a population. Statistics deals with the movement of the population as a whole. e.g. A single car may move at 30 mph. The total car population may have an average/mean speed of 20 mph.
What are importance of biostatistics in clinical research?
Statistics in clinical research is collecting and organizing numerical and clinical data obtained from the study sites and analyzing and interpreting it to verify the results of the trials and decide if it is was a success and if the drug is fit for human consumption. Using statistics helps in reasonable prediction of the effects of the drug on humans, even though the individual responses to the drug vary from person to person. Statistics plays a central role in the entire process of clinical trial from planning, conduct, interim analysis, final analysis and reporting.

Techniques such as job shadowing, interviews, surveys, and workflow analysis can be used to gather information for role analysis.
Why does solubility play a role in a gravimetric analysis?
Solubility always has to be considered as a source of error in gravimetric analysis because what remains in solution, no matter how little, doesn't get measured (although, it can sometimes be determined indirectly). So, gravimetric results are always erroneously low due to this factor.
What is role analysis?
Role analysis involves the following steps: 1. The objective of a department and functions to be identified 2. The person will be asked to state his understanding of the role 3. The other role partners to be asked to clarify the expectation from the post. 4. Then the role will be clarified to the person. The role willl be a integration of diverse viewpoints expressed by various role partners. Role analysis provides greater clarity in roles. The role incumbent knows what is supposed to do on the job, keeping the perceptions of others about his job in mind. role clarity in turn leads to improved performance in the job.
