What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Abolfazl Ghoodjani

Hello Atikhom Thienthong SPSS itself produces and presents such possibilities for you.

Atikhom Thienthong

Thank you for your quick response and useful information. Can you share some resources about the interpretation and presentation of the results using predicted probabilities? I would like to know how to compute predicted probabilities for categorical independent variable with 2-3 values.

Abolfazl Ghoodjani Which one is the predicted prabability since there are two different sets?

What do you mean by two different sets?

Predicted category or Predicted category probability?

Abolfazl Ghoodjani Sorry for my unclear response. Well, if I would like to report predicted probabilities of the outcome variables, which row represents the probabilities: PCP_1 or ACP_1? Thank you again for your time. I can't find this from other resources.

PCP. The results of this column are also obtained due to the selection of the Predicted category probability option. If you pay attention, the data in this column is the same as the largest number in the EST2, EST1 and EST3 columns. In other words, the numbers in this column can be seen as the probability of each person being placed in the PRE column.

ACP. The results of this column are obtained due to selecting the Actual category probability option. It is also very simple to understand. The numbers in this column show the probability of each person being placed in the level and the actual and observed group of the person. For example, in the picture I sent, person number eight is interested in mathematics. This article is specified from the Subject column. Now, based on the polynomial model, it is obtained that the probability that this person is interested in mathematics is equal to 26%.
