Hello. There are three variables (V1, V2, V3) which were tested in five time points simultaneously. In order to explain the changes of V2 and V3 from the point of V1, I want to calculate the correlation of V1&V2 and V1&V3, because previous studies showed that V1 can affect V2 and V3. From my data, I found V1/V2 was decreasing and V3 was increasing during the test period. The trend was consistent with the past relevant results of V1&V2 and V1&V3. Is there any methods to perform this calculation? Thanks~ |

If you want correlations ask for SAMPSTAT or TYPE=BASIC. |
