Hello,
So how do calculate a trend please for a set of time series data where the data values are binary thus:

000100111100010010101111000010101010101010000010111110000110

I know this must be real simple but I can’t seem to find a simple reference.
Many thanks IMK

Hello HallsofIvy and many thanks for your reply.
The best way I can describe what I mean be the Trend is as if you plot the data sequence as a graph in Excel and then add a trend line you can see if the number of one's to zero's is rising or falling. Any I had a soak in the bath on the problem and well I think it is simple arithmatic, unless I have mist something.

1. How do you calculate a trend line?

To calculate a trend line, you need to first plot the data points on a graph. Then, using a statistical software or a graphing calculator, you can use linear regression to determine the best-fit line that represents the trend of the data.

2. What is the purpose of calculating a trend?

The purpose of calculating a trend is to analyze the overall direction and pattern of a set of data over time. It can help identify any potential relationships between variables and make predictions for future data points.

3. What is the difference between a positive and a negative trend?

A positive trend indicates that the data is increasing over time, while a negative trend indicates that the data is decreasing over time. The steepness of the trend line can also indicate the rate of change.

4. How do you interpret a trend line?

A trend line can be interpreted by looking at its direction, steepness, and closeness to the data points. It can also be compared to other trend lines or used to make predictions for future data points.

5. Can a trend line be used to determine causation?

No, a trend line alone cannot determine causation. It can only show a correlation between variables. Further analysis and experimentation is needed to establish a causal relationship between variables.
