Statistical analysis results of muscle fiber counts.
FIBER_COUNT_STATS
An object of class data.frame
with 40 rows and 19 columns:
character; the measurement being tested. All "Fiber Count".
factor; the age of the rat at the beginning of the training protocol. Levels: "6M" (Adult) and "18M" (Aged).
factor; the sex of the rat with levels "Female" and "Male".
factor; the muscle that was sampled with levels "LG" (lateral gastrocnemius), "MG" (medial gastrocnemius), "PL" (plantaris), and "SOL" (soleus).
numeric; Exploring Compositional Data with the CoDa-Dendrogram: "the natural logarithm of the ratio of geometric means of the parts in each group, normalised by a coefficient to guarantee unit length of the vectors of the basis" (Pawlowsky-Glahn & Egozcue 2011).
factor; the comparison between groups. All contrasts are differences between the 8W and SED group means ("8W - SED").
character; interpretation of the value in the
estimate
column. All "difference of means" (difference between group
means, as specified by contrast
).
numeric; difference between the means of the groups as
specified by contrast
.
numeric; the standard error of the estimate.
numeric; lower bound of the 95% confidence interval.
numeric; upper bound of the 95% confidence interval.
character; the type of statistical test.
numeric; the value of the test statistic.
numeric; the number of residual degrees of freedom.
numeric; the p-value associated with the statistical test.
numeric; the adjusted p-value.
logical; TRUE
if p.adj
< 0.05.
character; the statistical model used for testing.
character; the model formula. Includes the response variable, any transformations, and predictors.
