7 Regression analysis.
Allows the calculation of the charge – distance table in a blast with the recorded data.
1.
Regression adjust window:
Displays the regression adjustment, with the adjustment line,
security line and the different points used for the study.
2.
Charge – distance table window:
Displays a graph with the distance (X axis) and the charge
(Y axis). To know the maximum charge allowed for a specific distance, find the distance in the
X axis, cut the blue line with a perpendicular and use a horizontal line at this point to find the
charge value. The magenta lines limit the area where the study is reliable.
3.
Component:
Enables or disables the components for the adjustment and / or show the graph.
4.
Charge – distance table data:
Enter the maximum and minimum distance for the charge –
distance table, and the maximum vibration value allowed.
5.
Advanced options:
Enter the confidence level of the security line (usually 95 %). By default,
the program will calculate the
best fit
line, but it is possible to force the alfa / beta relation.
6.
Data button:
To input the data for analysis. A dialogue box will appear to enable data input.
7.
Calculate button:
Calculates the regression analysis after the essential data has been added.
