Table 2. Results from a generalized linear model predicting frequency of microsatellite mutation, defined as number of variant reads per total number of reads.
| Predictor | T-value | P-value |
|---|---|---|
| Asexual/sexual | 1.4 | 0.16 |
| Copy number | 15 | <2 × 10−16 |
| Uniformity | 10.8 | <2 × 10−16 |
| Motif length | −9.6 | <2 × 10−16 |
| Motif GC-content | −4.9 | 9.9 × 10−7 |
| # Promoters | −3.5 | 0.00053 |
| Transcript abundance | 5.0 | 8.0 × 10−7 |
Transcript abundance was from tiling array data by Xu et al. (59). Null deviance from the model was 179 on 2168 degrees of freedom and residual deviance was 128 on 2161 degrees of freedom. The variance inflation factors were <1.3 for all predictors.
