### What is an Employee Portal?

An Employee Portal, sometimes known as an HR Portal, is an online employee engagement platform that puts a range of HR services at the employee’s fingertips. From providing employees with access to helpful HR content and self-service functionality that answers their questions, to Live Chat and case tracking, an Employee Portal enhances the employee service experience, which increases employee satisfaction and engagement levels.

It is also a communications and change management tool, enabling HR to effectively engage with their employees and support the management of change and development within the organization. Additional benefits include increased workforce productivity and greater efficiency of HR operations.

### What Is a Human Resource Portal?

A portal for human resource portal, also known as an HR portal is an internal access point to employees of a company who can gain access to HR-related information and other details regarding their work. It also serves as an entry to outside job applicants as well as potential candidates. HR portals are typically interactive and dynamic. They are not merely repositories for benefits or other information about the workplace.

The aim of an HR portal is to simplify and centralize data so that it’s easy for employees to access the information they require. For instance, when handbooks, benefits enrollment details, as well as other data are accessible through the portal, companies can save money by cutting down on printing costs and the time spent in distribution. (HR portals are usually secured, which means that employees typically need login credentials to access the company’s information.)

HR portals are also able to connect HR resource staff with employees (and vice from one to the other) in addition to reducing email and phone calls between them. If employees are able to access the information they require for themselves, they will not have to engage HR personnel.

05/04/2021 · This proof will be useful later on as we establish the R squared statistic, which is used to measure the quality of our fit.

## regression – Total sum of squares(TSS) is not equal ESS +RSS, …

TSS = ∑ i ( y i − y ¯) 2 = ∑ i ( y i − y ^ i + y ^ i − y ¯) 2 = ∑ i ( y i − y ^ i) 2 + ∑ i ( y ^ i − y ¯) 2 + 2 ∑ i ( y i − y ^ i) ( y ^ i − y ¯) = ESS + RSS + 2 ∑ i ( y i − y ^ i) ( y ^ i − y ¯). @hxd1011 is telling you that sometimes this cross term is 0, and sometimes it is not.

## FAQ prove tss=ess+rss

**What is the relationship between TSS RSS and R²?**

Relationship between TSS, RSS and R² TSS works as a cost function for a model which does not have an independent variable, but only y intercept (mean ȳ). This gives how good is the model without any independent variable. When independent variable is added the model performance is given by RSS.

**When total sum of squares is not equal ESS + RSS?**

Total sum of squares(TSS) is not equal ESS +RSS, when the model doesn’t include intercept of ones Ask Question Asked4 years, 9 months ago

**What does TSS stand for in statistics?**

TSS — total sum of squares. Instead of adding the actual value’s difference from the predicted value, in the TSS, we find the difference from the mean y the actual value. 5. Relationship between TSS, RSS and R²

**How to optimize the residual sum of squares (RSS)?**

Ordinary least square or Residual Sum of squares (RSS) — Here the cost function is the (y (i) — y (pred))² which is minimized to find that value of β0 and β1, to find that best fit of the predicted line. 2. Gradient Descent Gradient is one optimization method which can be used to optimize the Residual sum of squares cost function.
