## How do you do a life table in SPSS?

Analyze > Survival > Life Tables… Select one numeric survival variable. Specify the time intervals to be examined. Select a status variable to define cases for which the terminal event has occurred.

**How do you solve a life table?**

How we calculate the national life tables. Step 1: The life table starts with 100,000 simultaneous births (l0). Step 2: The life table population is then calculated by multiplying 100,000 (l0) by the mortality rate between age 0 and 1 years (q0) to give the number of deaths at age 0 years (d0).

### What is the difference between life table and Kaplan-Meier?

The main difference is the time intervals, i.e., with the actuarial life table approach we consider equally spaced intervals, while with the Kaplan-Meier approach, we use observed event times and censoring times. The calculations of the survival probabilities are detailed in the first few rows of the table.

**What is the life table method?**

Life tables date back many centuries and are a simple method of representing the mortality experience of a cohort of individuals. The very simple life table consists of a set of rows, each row representing a discrete period of time, say a year, and columns for different mortality status for the time period.

## What is a life table survival analysis?

A life table presents the proportion surviving, the cumulative hazard function, and the hazard rates of a large group of subjects followed over time. The analysis accounts for subjects who die (fail) as well as subjects who are censored (withdrawn).

**What is the Kaplan-Meier method used for?**

The Kaplan-Meier (KM) method is used to analyze ‘time-to-event’ data. The outcome in KM analysis often includes all-cause mortality, but could also include other outcomes such as the occurrence of a cardiovascular event.

### What is the P value in survival analysis?

The p-value (sig) is the probability of getting a test statistic of at least 3.971 if there really is no difference in survival times for males and females. As the p-value (0.046) is less than 0.05, conclude that there is significant evidence of a difference in survival times for males and females.

**What are the two ways to build a life table?**

There are two types of life tables:

- Period or static life tables show the current probability of death (for people of different ages, in the current year)
- Cohort life tables show the probability of death of people from a given cohort (especially birth year) over the course of their lifetime.

## How do you make a life table?

Methods of Constructing Life Table:

- x = Specific Age.
- dx = Number of deaths, at any particular age.
- fx = The number of persons surviving at age x to x + n i.e., at the age x + 1 = 1,00,000- 13,000 = 87,000.
- qx = Probability of death per person in the specific age i.e., total deaths occurred. (

**How do you describe a life table?**

A life table is a table which shows, for a person at each age, what the probability is that they die before their next birthday. From this starting point, a number of statistics can be derived and thus also included in the table is: the probability of surviving any particular year of age.
