Thank you for including the image URLs.

The charting could be due to the axis scales and the formula could be due to the forecasting methods chosen and/or the large number of observations.

If you can send through your template to contact [at] business-spreadsheets.com I will investigate and resolve this for you.

The independent variables do not have to be in the same units.  The regression equation is calculated based on the units for each independent variable.

Then the forecast can be entered (or prefilled) in the respective units for each variable.

If you want to use Cache and not the Multiple regression template, I suggest that you use the formulas and matrix processes required for multiple regression analysis.

To forecast the dependent variable all of the rows should be entered on the Input sheet to run the regression analysis first.

The Output sheet then allows to forecast the dependent variable.  If the forecast method chosen for an independent variable is "Leave blank", this assumes that predictive data will be entered for that variable such as that provided by external sources or analysis. 

Alternatively a forecast method can be chosen such as Linear, Exponential or Polynomial. These methods analyze the historical data trend to forecast the independent variable accordingly.  When all data the forecasts of the independent variables are then used in the regression equation to forecast the dependent variable reflecting the predictive regression relationships.

In this case, you should not include the row for which you want to predict in the Input sheet.  Run the regression on observations for which the dependent  variable exists.  Then choose to forecast with the option to Leave blank the independent variables.  Enter the data for the independent variables into the Forecast sheet to obatin the predicted value(s) for the dependent variable.

I am at the stage of evaluating your wonderful product, unfortunately, tarnished by few glitches. The first screenshot shows that for some reason the dependable variable's chart was not plotted. The second image portrays inconsistency in the forecast calculation formula within the same data column.

I'd appreciate if someone pays attension to my post. Thanks in advance!

Thanks for your quick reply. Unfortunately, it's a toy for my purpose. For example, the forecast is limited to 50 periods, whereas I need at least a full-year forecast (i.e. 365 days-periods), and the resulting formula establishing relation between dependent and the independent variables cannot be seen.
