COMPARISON OF REGRESSION TRENDLINES:

Comparison of two trendlines such as recovery versus feed grade or concentrate grade versus feed grade for two different conditions (e.g., Old Reagent vs. New Reagent).
This web app isolates the effect of the new condition (e.g., New Reagent) from that of another important parameter (e.g., feed grade).

The cleaned input data Excel file should have the parameters or variables'names in the top cell of each column at the top row (e.g., date/timestamp, throughput, feed grade, recovery, etc..).
The parameters' values are in the rows below the parameters'names. See example in table below.

Date	Mill availability	Throughput	Feed grade	Concentrate grade	Tailing grade
1/01/2022	92%	1200	1.21	25.4	0.150
2/01/2022	95%	1220	1.18	26.1	0.145
...	...	...	...	...	...
31/07/2022	97%	1180	1.19	14.8	0.147

The statistical comparisons of trendlines are easily completed without the pain of manually deleting, copying and pasting data for every condition.

To use:

Choose the pre-cleaned Excel (.xlsx) data file and click on "Upload to a table".

Select the trendlines to analyse (e.g., recovery vs. feed grade) and the two different conditions to compare (e.g., old and new reagents) .

Provide the confidence level at which the confidence interval is to be calculated (e.g. 90).

Click on "Calculate".

NOTE: Ensure the parameters you want to assess contain no empty values. To do that, select "delete rows" instead of "delete values" when cleaning the paremeters to assess during data cleaning.

large files may take time to upload, please wait.
