I need to place three tikz pictures side by side, and assign one caption to the triple and a subcaption to each tikz.

I currently use subcaption package and it works well. However, I need migrate to another template in which subfig package and subfloat command are used.
The subcaption package and the subfig package can not be used together, and it is impractical to modify the subfloat related codes. Hence, I need to use other method to achieve the same thing as the subcaption command.

This is what I want:

And I use these codes to generate it:

This is more of a long comment. In particular, this answer should not be awarded a green tick because I all that I am doing is rewriting marmot's nice solution in a more compact way. Up votes are, of course, fine:)

Rather than repeating this large chunk of code for each regression model I recommend defining a macro to do this. The only difference between the three different models used is which node is shaded. The code below defines a macro Model that takes one argument that tells it which node should filled. For example, Model1, Model4 and Model3 will produce the diagrams in the OP. This is done by adding a new style to each of the nodes and then changing the style for node #1 in the macro (the numbering of the nodes is the order that they appear in the OP).

As shown below, the output is the same as in marmot's solution but the code is shorter and easier to read:

You should be able to adapt this idea to typeset other similar models if you need them in other parts of your document. You might also want to include the minipage and caption in the Model macro.

To confirm that this works, here is the output:

It is possible to write the text with tikz below each figure. To do this, simply place this text in the node below the edge that joins the two lower circles:

This is more of a long comment. In particular, this answer should not be awarded a green tick because I all that I am doing is rewriting marmot's nice solution in a more compact way. Up votes are, of course, fine:)

Rather than repeating this large chunk of code for each regression model I recommend defining a macro to do this. The only difference between the three different models used is which node is shaded. The code below defines a macro Model that takes one argument that tells it which node should filled. For example, Model1, Model4 and Model3 will produce the diagrams in the OP. This is done by adding a new style to each of the nodes and then changing the style for node #1 in the macro (the numbering of the nodes is the order that they appear in the OP).

As shown below, the output is the same as in marmot's solution but the code is shorter and easier to read:

You should be able to adapt this idea to typeset other similar models if you need them in other parts of your document. You might also want to include the minipage and caption in the Model macro.

It is possible to write the text with tikz below each figure. To do this, simply place this text in the node below the edge that joins the two lower circles:

It is possible to write the text with tikz below each figure. To do this, simply place this text in the node below the edge that joins the two lower circles:

 path[line width=0.03cm] (temp1) edge node[shift=(.1,-.7),font=small] Subcaption (b) (temp2);
